Supplier progresses tech advancements

Chemicals reagents supplier and distributor Axis House has made advancements in projects pertaining to base metals, platinum- group metals and gold ores. Axis House supplies a large quantity of flotation collectors, which are used to separate minerals from waste rock, to Zambia and the Democratic Republic of Congo (DRC) – key regions with large base metals reserves. The company has been operational in the Copperbelt, in Zambia, and the DRC for about 20 years. These countries that host the Copperbelt are rich in copper and comprise the greatest concentration of copper deposits. The Copperbelt covers 31 328km2. “Axis House has specifically developed and tested flotation collectors, especially in copper/lead/zinc ores,” says Axis House sales representative Travis Myburgh. …

Balancing the Formula - IM - International Mining
Revadep proves its worth:

Axis House's Bernard Oostendorp, Technical Manager says its clients can benefit from increased metal recoveries while improving the working conditions of their staff and streamlining their processes with the implementation of its environmentally sensitive products. As Cherryl Thomas, Sales Manager,Africa says: "Environmental regulations are becoming stricter and requests for alternative reagents to common, but hazardous, chemicals (xanthates, NaHS and cyanide, ect) are increasing. "Axis House takes this into consideration during reagent development work for clients. Its xanthate-alternative sulphide collectors are being used successfully at several copper mines in Zambia, as well as platinum and gold mines in South Africa, according to Oostendorp. The European and Middle East markets has shown substantial growth in the last 18 months. This has sen multiple trials conducted and completed at copper-lead-zinc mines in Europe and Turkey, were sulphide collectors were successfully trialed in full-scale applications. Thomas said: "This allows Axis House to apply the application knowledge and market products to the operations processing similar ore types. Successful application of reagents also forms a new baseline from which development can take place. " Sulphide collectors are not all the South African-based company is working on. The company's Revadep Depressant range, engineered to target specific gangue minerals in the flotation process, has found favor with platinum group metals producers in South Africa. Thomas said the depressants have proven highly effective in the PGM flotation process by reducing floatable gangue like talc. The company is also targeting the Zambia copper flotation market with its Revadep Cu++ depressant formula, according to Thomas. Highly floatable carbon is also a problematic mineral in some of the operations in Zambia and the Axis House carbon depressant, Cu++, was successfully trialed at full scale", she said. In the DRC, the company's mobile precipitation plant, built specifically for cobalt miners to analyse the effect of dosage, process conditions and reagent type on different types of ore, is starting to be appreciated by miners too, Thomas said/ And, the development of a reagent range to remove cadmium in phosphate production has allowed Axis House clients to cost-effectively sustain phosphate output without bolting on processing units like ion exchange columns she added. At teh R&D stage of its Revadep depressants, Axis House is addressing the use of one of the more controversial reagents used across the mining industry, according to Thomas. "At development level, the focus is to expand the Revadep range to include selective depressants of sulphide gangue (pyrite, pyrrhotite) to replace or reduce the use of hazardous reagent like cyanide, "Thomas said.

Axis House grows with new Turkey site

South Africa-based Axis House, a leading reagent technology management company offering mining chemicals, flotation and mineral processing solutions since 2001, has become a major supplier and distributor of chemicals to the mining industry. As a result of extensive years of experience in the DRC and Zambia, Axis has announced the addition of a satellite office in Turkey that will service Northern Africa, Middle Eastern, European and Central African clients. Axis House Managing Director Justine Stubbs says: “We have spent years consistently pushing the boundaries of innovation for our diverse clients, and this satellite office is just the first step for Axis House in our scope for expansion into the main copper-producing regions globally as well as gold and platinum.” With a product offering, including both mining chemicals and mining consumables, the company believes that its expert team is always ahead of the curve. “We inherently believe that operational excellence can only be achieved through continuous and progressive innovation, and we are celebrating this progression with our new office in Turkey,” concludes Stubbs. The Axis House range of products includes mining chemicals for flotation – including proprietary flotation technology, primary and secondary collectors, the Hydrofroth™ range of frothers, and sulphidising agents – as well as depressants, thickeners, hydrometallurgical reagents and laboratory chemicals.
