Another major groups of deposits in the mafic layered complexes are platinum group elements and chrome deposits but unlike copper nickel massive sulfides they don't form as puddles on the floor of the intrusions they form in discrete layers well up in the magma chamber. The PGE's that's platinum Traditionally, platinum producers would stockpile this resource as waste material. However rising platinum mining costs and increased smelting capacity in China, enabled UG2 chrome to be sold as a by-product. The availability of UG2 chrome ore has upset the balance in the South African and global chrome ore

Chromium Statistics and Information

Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation's most important strategic and critical materials. Chromium use in iron, steel, and nonferrous alloys enhances hardenability and resistance to corrosion and oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important

Aug 24, 2020Chrome, a blackish mineral, is used to produce stainless steel. The Chinese are major shareholders in the Zimbabwe Mining and Alloy Smelting Company, known as ZIMASCO, one of the country's largest chrome-mining companies. They also invest heavily in gold, platinum and diamonds, giving them outsize influence over Zimbabwe's vast minerals

Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 C (3,375 F) and boils at 2,672 C (4,842 F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated

South Africa crucial to global chrome supply, Chromium

South Africa is an irreplaceable supplier of chrome ore and ferrochrome, which is, in turn, an irreplaceable component of China-dominated stainless steel production, global delegates to last week's well-attended Chromium 2017 conference heard. South Africa, as the dominant global chrome producer, last year delivered half of the world's production of chrome ore.

Marico Chrome – South Africa. Oman Chromite – Oman . Rand York Minerals – South Africa. Samancor – South Africa. Xstrata – South Africa. Markets. Ferrochrome markets consumed 93% of the chrome ore produced in 2009, with non-metallurgical markets accounting for almost all of the balance (save for 0.1% used as chromium metal).

Efficiency is enhanced through pelletising to cope with increasing volumes of fine chrome ore, in-house training programmes to overcome skills shortages, the proximity of the Port of Maputo, the use of more cost-effective upper group two (UG2) chromite ore recovered from platinum tailings, as well as radically reduced use of expensive coke.

Sep 19, 2018Chrome, which you may see as decorative trim on cars and motorcycles or to harden tools used for industrial processes, is an electroplated layer of chromium over another metal. Either hexavalent chromium or trivalent chromium may be used to produce chrome.

Feb 03, 2019Aluminothermic production of high purity chromium metal accounts for over 95% of chromium metal produced today. The first step in this process requires that the chromite ore is roasted with soda and lime in the air at 2000F (1000C), which creates a sodium chromate containing calcine.It can be leached away from the waste material and then reduced and precipitated as chromic oxide (Cr

PRICING NOTICE: Amendment to publication day of European, seaborne chrome prices. Fastmarkets will change the publication day of its European and seaborne price assessments, indices and indicators covering chrome ore and ferro-chrome to Tuesday, from

The upper group two (UG2) concentrate from a platinum group metal (PGM) mine in Rustenburg is also selected. Each mine produces 3 grades of chrome ore, namely lumps, chips, and concentrates. The lumps and chips of chrome ores are used as raw material and are directly fed in submerged arc furnace, while the concentrates of chrome ore

platinum group metals and chrome ore. Mobile belts • Metamorphic belts surrounding the Craton: • the neo-Archaean Limpopo Mobile Belt to the south, • the palaeo- Proterozoic Magondi to the northwest, and • the neo-Proterozoic Zambezi Mobile Belt to the north and northeast.

This seam is characterised by high levels of low grade chrome ore (UG2). Traditionally, platinum producers would stockpile this resource as waste material. However rising platinum mining costs and increased smelting capacity in China, enabled UG2 chrome to be sold as a by-product.

May 23, 2014Steel isn't officially stainless unless it has at least 11% chromium. Blade makers who use strip stock with 9% to 11% chromium often use the term Chrome instead of stainless, or in some cases as a marketing ploy. Platinum is used in an edge treatment to harden the edges and make them last longer. As always with blades, chrome or stainess, YMMV.
