    Gold And Copper Recovery From Flotation Concentrates Of

    The invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and or pyrite, hydro metallurgically. The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper (II) chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.Gold flotation, in the treatment of simple metal sulfide ore with less cyanide harmful substances in the ore, generally control the flotation pH = 7~9 with lime. it is usually necessary to control the concentration of lime in the leaching operation. For the gold concentrate cyanide plant, the CaO concentration of the general control.

    Leaching Of A Copper Flotation Concentrate With Ammonium

    The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24 up to 36 of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8 9 .Flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85 of chalcopyrite can be recovered with a copper grade of 14.5 in a single stage froth flotation. The chalcopyrite flotation concentrate can be sent back to chloride leaching circuits.

    Lime In Gold Ore Mining Process Flotation Cyanidation

    Gold was completely extracted by cyanide alone. The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been preg robbed. However, this mechanism did not explain the behaviour of the pyrite concentrate.When the content of copper and zinc minerals in gold is high ( 0.3 ), if the increased cyanide consumption is too high, but no economic loss is caused, flotation method can be used to separate part of qualified copper and zinc concentrate, then flotation tailings, and then extract gold by cyanidation.
