HAIB MINE DWS Landing Page

HAIB MINE. The Haib mine is located in Namibia approximately 3 km north of the Orange River and about 3 Km east of Noordoewer. It is a copper mine that has yet to be developed and has been investigated by several large mining companies over the last 50 years including the Rio Tinto Zinc mining group (RTZ).


the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 5070%, and the sulfur content of sulfidic ores is in the range of 1520%. Zinc concentration is in the range of 4060%, with sulfur content in sulfidic ores in the range of 2634%.


The ConRoast process is based on the removal of sulphur by roasting, followed by smelting of the deadroasted concentrate in a DC (direct current) arc furnace, using an ironbased alloy as a collector for nickel, copper, cobalt, and PGMs.

Copper Ore Dressing Process Xinhai

Copper ore refers to the mineral aggregate with a certain content of copper ore and can be recycled at the present stage. In general, copper ore is occurred in ore inside as sulfide, and associated with a certain amount of lead and zinc ore. Crushing–grinding–flotation is the most common copper ore dressing process. Taking Xinhai copperleadzinc ore dressing process as the example, we will briefly introduce .


A suitable and cheap method to process the sulfide copper containing chalcopyrite ore was investigated by thermochemical processes. The higher amount of copper leaching was 70 to 75 percent achieved by prior roasting at 650oC. The effect of various oxidants to increase copper leaching was also investigated during roasting of sulfide ores sample

Houllis (Intec Ltd, Australia) Email for correspondence: mail Abstract The Intec Process is a generic process for the production of pure base metals and precious metals from sulphides concentrates derived from copper, nickel, zinc and lead ores.

AZ of Copper Ore Leaching ALTA Metallurgical Services

AZ of Copper Ore Leaching 5 LEACHABILITY OF COPPER MINERALS • Leachability in sulphuric acid solutions varies enormously (see Table 1). Orebodies frequently contain a mix of minerals, commonly varying with depth. • Oxide minerals also are amenable to ammonia/ammonium carbonate leaching –reduction roast needed for silicates.

Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the ...
