    Why is it so expensive to extract copper from contaminated? Large areas of land, where this ore was once quarried, are contaminated with low percentages of copper sulfide Copper would be too expensive to extract from this contaminated land using the traditional method of quarrying and then heating in a furnaceFlowsheet for treatment of Copper Sulfide ores rich inminerals such as chalcopyrite with gold and silver as well as arsenopyrite The above flowsheet isCopper Sulfide Flotation Mineral Processing & Metallurgycopper sulphide leaching options as alternatives to the more conventional pyrometallurgical processing route of copper sulphides Three copper sulphide leaching and refining processes are discussed: total pressure oxidation, ferric sulphate leaching and copper chloride leaching The effect of mineralogyLeaching of Copper Sulphides SAIMM

    Coppercontaining rock, or copper ore, holds only a small percentage of copper Most of the rock is unwanted material, typically referred to as gangueThere are two main types of copper ore that“It is a onestep process, directly just decompose the sulfide to copper and sulfur Other previous methods are multiple steps,” Sahu explains “By adopting this process, we are aiming to reduce the cost” Copper is in increasing demand for use in electric vehicles, solar energy, consumer electronics and other energy efficiency targetsA new way of extracting copper | MIT News |ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals Sulfides are not reduced with the most widely used reducing agents, carbon and hydrogen, because the free energy change for theROASTING OF SULFIDE MINERALS Wiley Online Library

    Copper is the most important nonferrous metal It is a ductile metal with very high thermal and electrical conductivity and is thus used mainly as a conductor of electricity and, to a lesser extent, heat Other uses include as a building material and as a constituent of various metal alloys such as bronze and brassSome of the advantages of quarrying include: creation of job opportunities, creates good landscaping, and income generating avenue The disadvantages of quarrying include: pollution, loss of settlement sites, and a life hazard to quarry workers Quarrying is one of the major dominant industries in places where granite, chalk, clay and limestone are foundWhat Are Some Pros and Cons of Quarrying?
