Sandvik to form new crushing and screening business area

Sandvik has decided to spin off its Crushing and Screening division into a new business area called Sandvik Rock Processing Solutions (SRP).

The reason for this structural change, which will happen as of January 1, 2021, is to further accelerate profitable growth within rock processing, based on Crushing and Screening addressing separate parts of the value chain and facing different competition to the other Sandvik Mining and Rock Technology divisions, the company said.

“Sandvik is market leading within rock processing and our Crushing and Screening division is a well-performing business with exciting growth opportunities,” Stefan Widing, President and CEO of Sandvik, said. “The business is today already operating quite independently from the rest of Sandvik Mining and Rock Technology, with its own manufacturing, sourcing and aftermarket. By establishing Rock Processing Solutions as a business area we will improve transparency and strengthen our growth ambitions within the area.”

In line with this move, Sandvik has appointed Anders Svensson, President of the Crushing and Screening division since 2016, to President of the business area Sandvik Rock Processing Solutions and a new member of the Sandvik Group Executive Management, as of 1 January 2021. Svensson joined Sandvik in 2008 and has, prior to his current position, had several different management positions within Sandvik and in Metso Minerals.

The crushing and screening business had, as a division within Sandvik Mining and Rock Technology, about SEK7.4 billion ($837 million) in sales and a 15.9% operating profit margin in 2019 with about 2,000 employees.

The Sandvik Mining and Rock Technology business area will continue to be led by Henrik Ager and will, as of 1 January 2021, change name to Sandvik Mining and Rock Solutions (SMR), the company added.

B&E International to help miners consolidate supply chains amid COVID-19

As mining companies cut back in efforts to remain viable under COVID-19’s demanding conditions, crushing and screening specialist B&E International is proposing a bold new approach to streamline mines’ supply chains.

According to Ken Basson, Director of Plant and Engineering at B&E International, mining suppliers and service providers need to be proactive in helping mines find sustainable solutions to the current challenges.

“COVID-19 will undoubtedly reduce demand for certain commodities, and, with geopolitical uncertainty, we are likely to see increased commodity price volatility,” Basson says. “This is leading most mining companies – especially juniors – to try to strengthen their balance sheets.”

To do this, there are inevitable cuts in capital expenditure and even operating expenditure. He says the time has come for mining suppliers to streamline the delivery of their services and products, and even to assume more of the day-to-day risk facing mining operations.

“At a time when mines are demanding even higher efficiencies and more plant uptime due to tough trading conditions, the post-COVID environment is expected to present a number of logistical and supply chain constraints,” he said. “To cut through this double-whammy, suppliers need to be helping to consolidate supply chain networks. This is the only way of minimising procurement expenses while limiting process plant outages due to critical spares being unavailable in time.”

A range of other imperatives also need to be addressed at the same time, he says. These include the growing demand for mines to support in-country job creation and local skills development, as well as local manufacturing and procurement. This means less reliance on costly expatriate skills, whose movement around Africa may, in any event, be restricted by COVID-related regulations.

“To streamline the supply chain, B&E International is forming strategic partnerships with key suppliers, to integrate their respective service offerings with ours,” he says. “This gives the mine the advantage of dealing with fewer supplier interfaces. We also take over the responsibility of ensuring that our partners – and their products – perform to expectation.”

He highlights that B&E International – with a 40-year legacy in contract crushing, screening and mineral processing services – has expertise across the process supply chain. With experience across commodities including coal, copper, diamonds, gold, iron ore, manganese and aggregates, the company engineers cost effective solutions in various conditions around Africa, he added.

As one of the few companies in South Africa that both builds and operates its own equipment, B&E International is extending its level of vertical integration through this collaboration with strategic partners.

“Not only do we design, manufacture and install complete processing plants across various commodity sectors, but we also operate and finance these facilities,” Basson says. “This places us in a unique position to partner with mines to reduce their capex, opex and risk.”

The company offers a build, own, operate and transfer model of plant procurement, ensuring a mining company of its planned throughput while also fixing the exact cost of that production, he says.

As part of its market offering, it already conducts optimisation and debottlenecking studies for mineral process plant operators. It also provides plant maintenance contracts, in which it will operate and maintain a customer’s process plant on a toll basis, charging a fixed rate per tonne. Other current services include plant audits, optimisation studies, dust extraction, sampling and breaker systems for oversize run of mine treatment.

“A vertically integrated service offering to mines holds great value for both greenfield and brownfield sites,” Basson says. “As important is our experience in developing local skills wherever we operate – with both formal and hands-on training.”

He highlights that this approach empowers the customer to retain their future options in how they will operate their plants, depending on their internal success and broader economic conditions.

Wood and Cementation Americas complete Terra Nova Technologies deal

Wood says it has completed the sale of conveyor systems business Terra Nova Technologies (TNT), close to six weeks after the deal was announced.

Following a strategic review of its portfolio, Wood identified potential asset disposals which were expected to generate proceeds in the range of $200-$300 million, with the TNT sale making a “good contribution to the asset disposal program”, it said.

The TNT business was sold to Cementation Americas, a firm owned by Murray & Roberts Holdings Ltd, for $38 million.

Back in late-March when the deal was announced, David Kemp, Wood Chief Financial Officer, said: “Terra Nova Technologies has a strong track record in delivering material handling equipment to our customers. Wood’s strategy going forward is to focus on asset-light solutions rather than the manufacture/fabrication of equipment.”

Cementation Americas said TNT has earned a solid reputation for providing quality design, supply and commissioning services for crushing and screening plants, overland conveyors, heap leach systems and mobile stacking systems for waste and dry tailings.

Justin Oleson, President of Cementation Americas, said at the time: “The purchase of TNT fits well within Cementation’s strategy to improve our ability to serve clients, both geographically and across the mining value chain. The combining of Cementation and TNT complements both our underground and surface design/build portfolios, and better positions Cementation to support our client’s total mining needs.”

Metso and allmineral equipment arrives at La Parrilla tungsten project

W Resources is on course to hit its production goal at the La Parrilla tungsten project in the southwest of Spain, with crushing equipment arriving on site.

In a project update, the company said overall La Parrilla construction had accelerated during the summer months with construction completion of the crusher, jig and mill on schedule for the December quarter, and completion of the concentrator in the March quarter of next year – the same quarter it plans to start production.

La Parrilla is envisaged as a scalable project, starting up at 2 Mt/y to produce some 2,700 t/y of tungsten concentrate and 500 t/y of tin concentrate, before an expansion to 3.5 Mt/y and beyond.

W’s latest update said capital expenditure was tracking below budget, with engineering and procurement now both over 90% complete.

All major contracts have been placed, with 81.3% of the planned €27.1 million ($31.5 million) spend committed. The company also noted plant civil works were complete, concrete works for the crusher had been laid and works for the jig were underway.

Steel erection for the crusher was advancing quickly, the company said.

The primary Metso equipment for the 350 t/h crushing and screening circuit, which includes four HP300 cone crushers, a C130 jaw crusher, a VF500 vibrating feeder, MB352 rock breaker and MF2473 screen, were on site for “just in time installation”, W said.

W noted that primary allmineral equipment for the jig is arriving on site and allmineral confirmed the jig project was on schedule.

With a throughput of 350 t/h, the two alljig® jigs (one, pictured arriving on site) will provide grading, enrichment and cleaning of the pre-ground ore.

The alljig process involves the feed material initially being fluidised with pulsed water, with the grains graded according to density. The jigs separate the specifically lighter scheelite-poor yield from the specifically heavier scheelite-rich ore from the stratified material bed, allmineral said.

The processing plant, with a capacity of 155 t/h connected to the pre-concentration stage through the alljig jigs, will ensure tailings are separated from the valuable material, thereby achieving a 65% WO3 recovery, the company said.

The fines produced in several processing stages are to be recovered in a separate circuit.
