The mineral processing plant manufacturer Appropriate Process Technologies (APT) is currently changing its strategy to target platinum miners, in Zimbabwe. The company is designing a new modular platinum gravity recovery system that can be used to process primary ores. The firm''s chief executive, Kevin Peacocke, said in a statement that: We are focusing more on

· It also produces 134,000 ounces of platinum annually. As many nickel ores also contain PGMs, Vale is able to extract platinum as a byproduct of its nickelrefining process. The company takes PGMcontaining concentrates from its Sudbury, Canada, operations to a processing facility in Port Colborne, Ontario, which produces PGMs, gold, and silver intermediate products. 09. of 10.

· The concentrator treats platinum ore which is mined from the UG2 reef from various shafts in the Rustenburg area. Ores from these shafts are combined in receiving bins at the concentrator, or stored on common stockpiles if bins are full. Consequently, feed to the mill may vary from pure ores to blends of ores from the various shafts.

Platinum, in the form of the mineral sperrylite (PtAs2), is obtained as a byproduct of the nickel mining operation. Spanish people were the first Europeans to encounter the metal, although they found it a nuisance because of its similar appearance as silver. They referred to the metal as Platina, the Spanish word for silver. Although studied by a number of chemists in the mid18th

Platinum group metals are unevenly distributed within deposits of platinum ores. Their concentrations range from 2–5 g to several kilograms per ton in primary platinum ores, from tenths to hundredths (sometimes thouhs) of grams per ton in primary complex ores, and from tens of milligrams to hundreds of grams per cu m in placer deposits.

PGM minerals. Typical ores for PGMs contain ca. 10 g PGM/ton ore, thus the identity of the particular mineral is unknown. Platinum. Platinum can occur as a native metal, but it can also occur in various different minerals and alloys.

· The aim of this paper is to investigate the effects of ore blends on the mineral processing of platinum ores. The study is conducted using a simplex lattice mixture design for a range of ores of relevance to the Waterval UG2 Concentrator. The main aim of the paper is to determine whether blends of ores display linear grinding and flotation characteristics or whether nonlinear effects occur, i

Minerals are natural compounds formed through geological processes. A mineral could be a pure element, but more often minerals are made up of many different elements combined. Minerals are useful chemical compounds for making new materials that we can use in our daily lives. In this chapter we are going to look at how to get the minerals out of the rocks and in a form that we can use. This is
