mining process autoclaves

Valves for nickel autoclave high pressure acid leaching ...Autoclaves are used in mining and minerals processing to extract metals from refractory ore bodies. A typical process for autoclaves is high-pressure acid leaching (HPAL), which is often used to extract nickel from laterite ore bodies, but it can also be applied in copper and cobalt production.autoclave - Mining MagazineMining Magazine - Latest mining and investment news.

High Pressure Acid Leach - Caldera Engineering

The HPAL process works as follows: ore is mined and crushed to create a fine material. These fines are mixed with water to create a slurry which is then preheated. This hot slurry is pumped into an autoclave (a giant pressure cooker of sorts) where acid is added.The Mining Process - Newmont Corporation - About UsAn alternative to an autoclave is a roaster, a very high temperature oven that is often used instead of an autoclave if the ore to process contains a large amount of organic carbon. Roasting uses heat and air to burn the organic carbon into fuel and to burn the sulfur off ore, which we heat to 932 to 1,202 degrees F.Processing Options: Roaster/Autoclave - Gold Companies ...Roasting and Autoclave. Roasting is a stage in processing used to make highly refractory ores amenable to cyanidisation. Like BIOX, roasting effectively does in hours what natural weathering does over thousands of years – the oxidisation of sulphides. ... Roasting is a high energy and high cost process and so only the most refractory ores ...Autoclave & Oven Systems - Home - ASC Process SystemsAutoclave & Oven Systems.
