The basic ore slurry can be combined with a solution of sodium cyanide or potassium cyanide; many operations use calcium cyanide, which is more cost effective. To prevent the creation of toxic hydrogen cyanide during processing, slaked lime ( calcium hydroxide ) or soda ( sodium hydroxide ) is added to the extracting solution to ensure that the acidity during cyanidation is maintained over pH strongly
Copper is lower in the reactivity series of metals and would be easier to extract from its ore. Sulfide ores of copper can be reduced with silica SiO2 and roasted at about 1200oC. Iron ore is
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
A metal ore is a mixture of minerals containing the metal, and other materials in the rock, from which it is economically viable to extract the metal. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Most metal ores occur as

Aug 01, 2007#183; The principle source of potassium, and the one from which we obtain most of our source, is potash. Other major potassium ores includes anorthoclase, microcline, orthoclase, potassium feldspar, and sanidine. All 5 of these are collectively called feldspars, and between feldspars and potash, that really covers a lot of potassium.
Potassium and phosphate were extracted at low temperature by acid hydrolysis process to decompose a new type of associated phosphorus and potassium ore.
07/12/2012#0183;#32;The method used to extract a given metal from its ore depends upon the reactivity of the metal and so how magnesium is oxidised when it reacts with oxygen to form BBC GCSE Bitesize: Methods of extracting metals. Most everyday metals are mixtures called alloys. Thus the method of extraction of a metal from its ore depends on the
