DELKOR India to supply vacuum belt filters to two mining operations in the DRC

DELKOR India has been contracted to provide DELKOR Horizontal Vacuum Belt Filters, together with ancillaries, for two operations in the Democratic Republic of the Congo (DRC).

The orders included supply of a 162 sq.m filter for a copper project in Katanga, which was commissioned in 2022, and supply of a 110 sq.m filter for a cobalt processing plant in the Lualaba province. The latter was commissioned in 2020.

The scope of work for both contracts covered design, engineering, manufacture, supply (ex-works) and supervision.

Both filters were designed to achieve maximum recovery of water and produce a drier filter cake, DELKOR says. However, in the case of the 162 sq.m horizontal belt filter, the water is removed from the cake to repulp with acid in the downstream unit operation in preparation for the leaching process.

The filters were manufactured mainly from high-strength and corrosion-resistant stainless steel suited to the process requirements and were supplied in a knockdown state for easy and efficient erection on site.

These two projects reinforce DELKOR India’s long-standing relationship with the client, with earlier contracts including:

  • One 145 sq.m and one 64 sq.m horizontal vacuum belt filter;
  • Various thickeners of several capacities, including a high-rate thickener; and
  • Test work and design for a belt filter and high-rate thickener.

“We are proud to have been part of the establishment of such important projects,” Indu Bhushan Jha, DELKOR Managing Director, says. “These contract awards provide further examples of DELKOR India’s commitment to maintaining the loyalty of its client base through superior service and best-of-breed technologies.”

Weir Minerals and Andritz expand tailings processing collaboration with IsoDry

Weir Minerals and Andritz have signed an agreement at MINExpo 2021 expanding their shared commitment and strategic cooperation to supply equipment for processing tailings in the mining industry.

The foundations of this agreement have been built on a shared understanding and vision to enable the sustainable and efficient delivery of the natural resources essential to create a better future for the world, they say.

Since 2018, Weir Minerals’ and Andritz’s partnership has seen them collaborate on joint tailings projects. This shared history as partners has reinforced their abiding belief that, together, both Weir Minerals and Andritz are stronger, they said.

This shared success has led both Weir Minerals and Andritz to renew their ongoing commitment and announce they’ll be expanding their offer to all regions around the globe.

Using Andritz’s proven separation and dewatering technologies, Weir Minerals says it has strengthened its whole-of-mine capabilities, showcasing market-leading products from extraction to comminution, mill circuit and tailings management.

“Weir Minerals has been providing tailings solutions for decades; we have dedicated research facilities – the Weir Technical Centre in Melbourne, Australia, and the Sustainable Mining Centre in Venlo, Netherlands – that are challenging conventional ways of thinking about tailings, while also developing practical, innovative and sustainable solutions that will reduce operating costs and improve safety,” Ricardo Garib, Weir Minerals Division President, said.

“Decreasing ore grades mean that mines are producing more tailings than ever before. One of the challenges with tailings management is that there cannot be a one-size-fits-all approach; each mine requires a tailored solution that carefully considers the minerals being processed, as well as the site’s climatic and geological conditions. Weir Minerals prides itself on having both the expertise and equipment that allows us to partner with miners everywhere to plan and implement tailings solutions based on their operations’ unique challenges and this agreement with Andritz enhances those capabilities,” he said.

Steve Huff, President Andritz Separation, said: “Andritz has a long history working across a range of different industries. We are very proud of the work we’ve done with Weir Minerals; together, we’re excited about continuing to provide a joint offering of sustainable and value-added tailings solutions. Both companies bring a different expertise and know-how to the partnership; we complement one another and ultimately, it’s our customers who’ll benefit.”

Tailings management forms an important element of Weir Minerals’ broader integrated solutions approach, which considers problems and challenges from all perspective and draws on a range of experts – process engineers, design engineers, product experts and materials scientists, among others – to identify potential challenges and opportunities and provide tailored solutions.

Charlie Stone, Weir Minerals VP Sales and Business Development-Mill Circuit, said: “This latest agreement enhances our overall tailings offering and enables us to provide our customers with a complete tailings solution. Under the brand name IsoDry, we will continue to offer customers a range of mechanical separation technologies, such as thickeners, filter presses, centrifuges, and vacuum belt filters.”

Weir Minerals has strengthened its tailings team to support the market and ensure that it can provide innovative solutions based on each customer’s specific requirements.

The agreement provides the opportunity for potential future collaboration on technology, harnessing Andritz’s separation technology in conjunction with Weir Minerals’ minerals and tailings processing technology. Many of these products – Warman® pumps to transport fluid tailings, GEHO® pumps to handle paste, Cavex® hydrocyclones to dewater tailings and the Multiflo® range of dewatering solutions – have been integral to helping miners manage their waste for generations, they said.

Weir Minerals and Andritz have also reiterated their shared commitment to sustainability; it is an essential part of both their business and corporate strategies. Both companies say they have outlined ambitious plans to reduce their carbon emissions, while their approach to ESG initiatives extends to all aspects of their organisations.
