Advantages of method to leach graphitic shale ore

how to quantify graphite contents in rock powders?the method we use is precisely weigh a powdered sample (0.1 to 1 gram aliquot); leach with dilute hcl to remove carbonate carbon; roast in leco furnace at 425 c until weight is stable (removesca1062918a milling of graphitic or carbonaceous oresabstract of the disclosure a process for milling g bearing graphitic or carbonaceous ores is disclosed. the process consists in grinding the ore to approximately 85% minus 200 mesh in the barren solution which remains after precipitation of the g in the regular cyanidation process and to which is added a predetermined amount of a graphite inhibitor such as kerosene.carbonaceous g ore treatment methodflotationcyanide leaching with carbon or resin in pulproastingchemical oxidationthe simplest method of treating a carbonaceous ore is the method described by r. w. nice (1971) at the mcintyre porcupine mine where the carbon, which contains very little g, is floated off and discarded. the remaining ore is then responsive to cyanidation. this does not work at carlin because the carbonaceous compounds have a high g content. a considerable amount of flotation work was done on carlin ores, however, tosee more on 911metallurgistestimated reading time 8 minstreatment of carbonaceous refractory g ores sciencedirectjan 01, 1991· in addition the paper describes the various precyanidation treatment methods for carbonaceous refractory g ores namely, (1) flotation and depression, (2) blankinggraphitic and pyritic black schist and black shalegraphitic and pyritic black schist and black shale conduction mechanisms in highly polarizable rocks and their impact on em surveys j.h. börner 1 , f. girault 2 , d. kiyan 3 , m. bhattarai 4 , l. b. adhikari 4 , v. rath 3 , f. perrier 2 and k. spitzer 1 ore permeability methods of evaluation andore permeability methods of evaluation and application to heap leach optimization.
