roasting copper ore Solutions Just Right For You

EP0011475A1 Recovery of tungsten values from tungsten A method of recovering tungsten values from a high grade tungsten bearing ore or concentrate such as scheelite or wolframite includes the steps of roasting without fusion the ore or concentrate in the presence of a reactive composition selected from the group of an alkali metal chloride an alkali metal carbonate and mixtures thereof and Roasting is a relatively common pyrometallurgi-cal ore pre-treatment process that continues to see application today and saw even greater application in the past The two most common purposes for roasting of arsenical sul-phide ores are (1) to improve the extraction of refractory gold and (2) to remove As from copper ores prior to smelting The

Sinter Roasting/Blast Roasting Fine ore concentrate have to be agglomerated before they can be charged in a blast furnace Treatment of sulphide ore in a sintering machine where roasting and agglomeration take place simultaneously Charge = (fine ore+ moisture) as layer of 15-50 cm thick on revolving belt Combustion is done by burner Speed is adjusted - roasting should be completed before

Copper Mining and Processing Processing of Copper Ores Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes which will ultimately be made into products for everyday use The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and

In metallurgy the operation of roasting as a preliminary to chlorination has for its object the expulsion of the sulphur arsenic antimony and other volatile substances existing in the ore and the oxidation of the metals left behind so as to leave nothing (except metallic gold) which can combine with chlorine when the ore is subsequently treated with it in aqueous solution

Sulfide Ore Processing Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur

Roasting is a technique by which carbon and sulfur react with metal to separate the ore For example copper acetate is reacted with chemicals to separate the copper ore and residue This mix is reduced which involves placing it under extremely high temperatures injecting a reagent (such as hydrogen or carbon dioxide) and melting away the metal
