usually present in the silica sand are free and coated iron oxides clay titania and upgrading of silica sand requires partial removal of iron Nickel Processing Extraction And Refining Britannica In the next step iron in the matte is converted to an oxide which combines with a silica flux to form a slag this is done in a rotating converter of the type used in copper production the slag is drawn off leaving a matte of 70 to 75 percent nickel Iron Smelting Essential Humanities Flux is any material that tends to bind with the unwanted minerals in an ore collecting them into globs termed slag for easier removalthe most commonlyused material for flux is limestone 20 thus when the pit furnace was allowed to cool the iron bloom was dotted with globs of slagthe bloom was subsequently worked quotwroughtquot by hammering to remove the slag 1 yet a small amount of 123 Primary Copper Smelting Charge material of copper concentrate mixed with a siliceous flux often a lowgrade copper ore is heated in air to about 650176c 1200176f eliminating 20 to 50 percent of the sulfur as sulfur dioxide so2 portions of impurities such as antimony arsenic and lead are driven off and some iron is converted to iron oxide Copper Production How Is Copper Made Thoughtco Sep 26 2019nbsp018332copper is typically extracted from oxide and sulfide ores that contain between 05 and 20 copper the refining
