US8540951B2 Process for extracting metals from
A process for extracting metal values from ores or residues is disclosed. The process mentioned above is mainly suitable for aluminoferrous ores such as bauxite, titanoferrous ores such as ilmenite, or residues such as red mud waste. The process involves pulverizing the ore and/or residue and mixing with a carbonaceous material, followed by smelting the iron values and slag in the mixture to
extracting metals from ores fertis.pl
Metals are often found as compounds in ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon.
US5074910A Process for recovering precious metals
The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300° and 600° C. while stirring. The process converts precious metals in the elemental and sulfide forms into
