2018年1月6日 PGMs extraction by cyanidation show poor kinetics at room temperature and atmospheric pressure, thus, effective leaching of the PGMs is carried out at high temperature and pressure. In cyanide leaching process, the rate of reaction rate is proposed to be controlled by a surface chemical reaction, which is similar to gold cyanidation

The market for platinum-group elements (PGE) is profitable, but difficult to enter for newcomers. The main difficulties are in extraction technology, economics and marketing. Novel metallurgical processing technology may offer a route for the development of currently sub-economic PGE deposits that are amenable to surface mining.

2 天之前 Platinum (Pt) is a rare and valuable metal that is widely used in various industrial applications due to its unique properties. Platinum ore refers to the naturally occurring rocks or minerals that contain significant concentrations of platinum, usually in the form of platinum group minerals (PGMs) and associated minerals. Platinum ore is typically found in

2020年4月22日 Abstract Platinum group metals (PGMs) are considered critical raw materials, thus their recycling and re-use is of outmost importance. Among the PGMs, platinum (Pt), palladium (Pd) and rhodium (Rh) are the basic metals used in catalytic converters. Concerning the stringent EU standards for emission control imposed to car

The Great Dyke, Zimbabwe, contains over 800 million ounces of platinum and approximately 20 million ounces of rhodium. However, about 10% of the ore is oxidized and cannot be processed with current recovery methods. A conventional flotation-smelting process has been proposed to recover the platinum group metal (PGM) values from the sulfide ores.
