Trollope Mining Services boosting southern African reputation with Metso hybrid crushers and screens

Amid growing demand for its crushing and screening services, Trollope Mining Services, one of the largest open-pit mining contractors in Africa, has continued to increase its fleet of Metso machines from Pilot Crushtec, the South Africa-based company says.

With nearly 500 pieces of equipment in its fleet, Trollope has over the years established itself as the go-to contractor in the open-pit mining sector in southern Africa, it says. Currently operating in South Africa, Namibia and Botswana, the company has also previously executed projects in the Democratic Republic of the Congo and Guinea. The company operates across commodities including but not limited to coal, platinum, copper, andalusite, gold, phosphate, lithium, iron ore, manganese, diamonds and limestone.

To establish itself as a total solutions provider in the mining contracting fraternity, Trollope Mining Services added a crushing and screening division to its business in 2016. Managing Director, Guy Hopkins, says that in the past three years the division has seen exponential growth on the back of some major projects, necessitating an expansion of the crushing and screening fleet.

Following the fleet expansion program, Trollope Mining Services now operates a total of 15 machines. Of note is that the whole fleet is made up of only Metso machines.

“We prefer Metso machines because of our experience with the equipment,” Hopkins says. “Fundamentally, the design and build quality of these machines are unmatched. Our buying decision is also influenced by the technological evolution of the Metso offering, which allows us to run ‘hands off’ operations. Apart from improved efficiencies, technology paves the way for improved safety on mining sites.”

Of its 15 Metso machines, six are dual-powered units, making Trollope Mining Services the biggest operator of Metso hybrid crushers and screens in southern Africa, confirms Charl Marais, Sales Manager at Pilot Crushtec. The dual-power fleet comprises two Lokotrack® LT120E™ jaw crushers, a Lokotrack LT330D™ cone crusher and three Lokotrack ST2.8E™ scalping screens. These were expressly purchased for a project in the Northern Cape Province of South Africa.

With their ability to have both electricity and diesel as power sources, Marais says dual-power solutions provide the best of both worlds – significant fuel savings and a marked reduction in carbon emissions. “Significant cost reduction is achieved when the machines are connected to the grid,” he explains.

Hopkins added: “Given the high cost of diesel, dual-powered solutions help reduce operating costs for our customers. In our experience, the cost of running bi-power machines off the grid is 1/20 the cost of running them off a diesel engine. There is therefore a major cost benefit for our customers’ operations.”

Apart from the Metso build quality, Hopkins says the aftermarket support from Pilot Crushtec is crucial to ensuring high uptime.

“In all our buying decisions, having a partner that we can trust for the long term is fundamental,” he said. “Pilot Crushtec plays a crucial role in supporting us with all the necessary spares and technical expertise to keep our Metso machines running.”

Trollope to take over mining at Lucara’s Karowe diamond operation

Aveng Moolmans and Lucara Diamond Corp have agreed to cut short a six-year mining contract at the Karowe mine, in Botswana, following equipment availability issues and difficulties with waste mining, the diamond miner said.

Moolman Mining Botswana, an Aveng subisidiary, was awarded the contract to deliver the full suite of mining services at the Karowe mine, including all drill, blast, load and haul functions for both ore and waste, in January 2017.

In Lucara’s June quarter results, it said the two companies had continued to work to “find a solution” to the problems experienced during the March quarter of 2018 and, following extensive discussions in May and June, both parties had agreed to terminate the contract at the end of 2018.

In the March quarter, ore mined volumes and carats recovered were as expected, but waste mining was lower than forecast at just under 4 Mt.

Lucara said performance stepped up “considerably” during the June quarter – with 4.4 Mt of waste mined – and continued through the month of July, the first full month of transition between Moolmans and new contractor Trollope Mining Services.

As a result of this, waste mining was still expected to be within guidance (13-16 Mt) for the year, while diamonds recovered were expected to total 270,000-290,000 ct.

Lucara said of the contractor transition: “The addendum provides for a transition period of up to six months to allow for a new mining contractor, Trollope, to gradually assume responsibility for both ore and waste mining from Moolmans, with full responsibility for all mining activities to be the responsibility of Trollope as of January 1, 2019.”

Trollope, based in Johannesburg, South Africa, has previously worked with companies such as Exxaro, Anglo American, Harmony Gold and BHP.

Aveng Moolmans took over from former contractor Eqstra Botswana in 2017, which also had its contract cut short.
