gold cyanide solution, laboratory bottle test method this is one method for doing cyanide bottle leaching tests for determining the 'leachability' of gold and silver by leaching with cyanide. take the ore to be leached and crush it to a size that will fit into a pulverizer usually -1/4' . then feed the ore to a pulverizer and grind to -100 mesh.
how the method of pre-lime treatment affects gold leaching. the mines et usine de salsigne in the south of france is cyaniding 100 tons a day of a complex gold ore containing besides arsenopyrite, pyrite, and pyrrhotite, sulphides of bismuth, lead, zinc, and nickel as well as small amounts of chalcopyrite.
ore processing waihi gold. ore processing is a 24 hour operation. ore is stockpiled 1 at the processing plant, and the process begins by feeding the ore into a hopper with a loader. the ore is conveyed, and lime is added 2 to raise the ph of the ore.
content. second ore is an ore with relatively higher liability to nacn leaching whilst the third one features a significant extent of potential cyanide consuming components other than au or ag, i.e. cyanicides. for determining the leaching behaviour of the ores bench scale bottle roll tests were used. common conditions for all
