Among such rocks are granite, aplite, gneiss, eurite, quartz-trachyte, syenite, andesite, basalt, diorite, gabbro, diabase, schists, porphyry and slate. These deposits seldom pay to work and in that case can hardly be called gold ores. J. E. Spurr writes—"Native gold has been found in both basic and acid rocks.

Bottle Roll Testing for Cyanidation of Gold Ores: …

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

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings …

Refractory Gold Ore Flash Roasting

Oxidized ores have been processed by these more straight forward methods. However, as oxidized ore deposits are diminishing in occurrence, refractory ores have risen in importance. Refractory gold ores are typically pyritic, arsenopyritic, and carbonaceous. The gold is present as the metal, and as very fine particles locked in the host minerals.

Metallurgical Test Work: Gold Processing Options, Physical Ore

Certain gold ores, mainly those containing sulfides, arsenides, or tellurides, are best treated by producing a flotation concentrate (Anderson, 1980, Jones and Woodcock, 1984, King, 1982). This is almost always the case in treating refractory gold ores, where the refractory nature of the ore is due to sulfide mineral species.
