What Is Silver Smelting with pictures

Feb 14 2021 0183 32 Copper-bearing ores that contain around 02 silver are first crushed and then smelted in a blister process that produces a waste product known as slime which contains up to 20 silver content The slime is then oxidized in an additional silver smelting furnace which removes all ore components except silver gold and platinum metals...

Extraction of Platinum Group Metals IntechOpen

Oct 02 2017 0183 32 Another innovation able to manage chrome-rich ores is the ConRoast process This process involves removing and capturing sulphur from the concentrate prior to smelting in a DC arc furnace Roasting a concentrate makes smelting more environmentally friendly it also enables furnaces to accept any proportion of chromite resulting in more...

Cobalt extraction

Recovery from copper-cobalt sulfide concentrat The ores are treated by a sulfatizing roast in a fluidized bed furnace to convert copper and cobalt sulfides into soluble sulfates and iron into insoluble hematiteThe calcine is subsequently leached with sulfuric acid from the spent copper recovery electrolyteOxide concentrates are introduced at this leaching step to maintain the acid balance...

Innovations Introduction to Copper Mining Extraction

The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals Such ores originate from sulfur-bearing volcanic magmas which have separated into metal sulfides and siliceous melts...

Copper Smelting Process

Modern copper smelters use processed copper ore fed into a flash furnace typically fired by oxygen which produces blister copper being further processed in a converter furnace Molten copper is poured from here into rectangular moulds the resulting ingots subjected to electrolysis producing a metal of 999 purity Copper can be recycled indefinitely without the base metal being compromised...
