Solvent extraction in southern Africa: An update of some

The copper Tailings Leach Plant at Nchanga, Zambia, was commissioned in 1973 with a capacity of 2800 m 3 /h. This was the largest SX plant in the world for more than a decade and is still operational today. South Africa witnessed the first commercial implementation of SX for the refining of the platinum-group metals.Copper-cadmium slag, a kind of hazardous metallurgical solid waste, has attracted attention in the fields of environmental protection and resource recovery because of its high output and richness of valuable metals. Ozone and chlorides were used to extract platinum group metals and gold and the leaching percentage of platinum, Platinum, palladium and gold leaching from magnetite ore,

A conceptual flowsheet for heap leaching of platinum

This is the case at Western Platinum Limited (WPL) where the concentrator plant produces, as a by-product, a low-grade concentrate from the secondary cleaning circuit containing up to 29 g/t of platinum group metal (PGMs), 0.36% copper and 0.74% nickel and less than 0.5% S. In the case of UG2 ores, this low-grade concentrate is also associatedThe major portion of platinum and palladium produced today from primary sources originates from the Bushveld Igneous Complex in South Africa. The most important reefs mined are the Merensky, Upper Group Two (UG-2) and Platreef (Cramer, 2001).Ore grades range from 3 to 8 g/t PGM, with associated nickel and copper in the 0.1–0.2% Direct leach approaches to Platinum Group Metal (PGM)

The extractive metallurgy of South Africa's platinum ores

The extraction technology for platinum-group metals (PGMs) has changed dramatically in the last 80 years, and the changes are likely to continue for years to come. This article will reviewPlatinum and other metals are very scarce materials widely used in the energy and transportation sector among other sectors. Obtaining Platinum is becoming more difficult due to its scarcity on earth and because of the high amount of energy and water used for its extraction. In this regard, the recycling of platinum is necessary for Catalysts Free Full-Text Platinum Recovery Techniques for a

Recovery and extraction of platinum from spent catalysts: A

So platinum recovery is cost-effective (Comisión Europea, 2018). One of the largest sources of platinum extraction from secondary sources is industrial spent catalysts. Based on the value of platinum and its amount in the waste of spent catalysts, its extraction and recovery have been considered. [[9], [10], [11]]; Zanjani & Baghalha, 2009Ramachandra used LIX 841 and Alamine 336 to extract platinum and palladium (A/O = 3), and then platinum and palladium were stripped with 0.5 mol/L thioureas and 0.1 mol/L hydrochloric acids, respectively.
