Advantages of extraction of copper from its sulphide ore equation

copper copper is a chemical element with the symbol cu (from latin cuprum) and atomic number 29. it is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.a freshly exposed surface of pure copper has a pinkishorange colorpper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterlinglakhmir singh chemistry class 10 solutions for chapter 3(b) give the name of one ore of iron. which iron compound is present in this ore? write its chemical formula. (c) describe the extraction of zinc metal from its sulphide ore (zinc blende). write equations of the reactions involved. (d) explain why, the galvanised iron article is protected against rusting even if the zinc layer is broken.the metallurgy of cyanide g leaching an introductionoct 20, 2014· refractory ores/solidsolution g in some ores, au can be locked inside the sulphide mineral matrix of the ore (so called solid solution), and the cost for the energy required to grind and liberate is simply too high to be viable. these are refractory ores and require a chemical, not simply physical, process to liberate g from thebioleaching bioleaching is the extraction of metals from their ores through the use of living organisms.this is much cleaner than the traditional heap leaching using cyanide. bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, g, silver, and cobalt
