characteristics of gold ore

Ore fluids were moderate temperature (~180°-240°C), low salinity (~2-3 wt % NaCl equiv), CO 2 bearing (<4 mol %), and CH 4 poor (<0.4 mol %), with sufficient H2S (10 –1 –10– 2 m) to transport Au. Ore fluids decarbonatized, argillized, and locally silicified wall rocks, and deposited disseminated pyrite containing submicron Au as Fe liberated from wall rock reacted with reduced S in the ore fluid.

Metallurgical studies by Resources Gold Technology begin with consideration of the information obtained in a pre-feasibility study. Gold processing routes are evaluated and a gold extraction process is selected. The characteristics of the gold ore are investigated from a representative sample of the ore

Oxidizing, acidic waters form via the disproportionation of magmatic SO2 (g), which generates abundant sulfuric acid and minor H2S. Temperatures vary widely (>400°–100°C), but salinities are generally low (<5 wt % NaCl equiv). There is rare fluid inclusion evidence for magmatic brines in some deposits.

Gold deposits are found in a variety of geological conditions, identifying these indicators of gold geology will increase your likelihood of finding gold.

On the pages I have images of native gold and platinum plus a variety of different ores for gold, silver and copper, plus info about these ores and where they are found. Mark Twain's Prospecting Adventures Young Sam Clemens (later to be known as Mark Twain) came to Nevada and contracted a very bad case of "Gold and Silver Fever".

Gold (Au), chemical element, a dense lustrous yellow precious metal of Group 11 (Ib), Period 6, of the periodic table. Gold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form.

Gold is an excellent conductor of heat and electricity. It is a soft, yellow, metal with a beautiful lustrous sheen. It is the most malleable and ductile of all the elements and a single gram can be beaten into a sheet one square meter sheet of gold leaf.

implies a rapid breakdown of pyrrhotite-rich ores. Dissolution of galena and arsenopyrite, if present, promotes the precipi-tation of a variety of Pb- and As-bearing metal sulfate and carbonate minerals (fig. 12-1; table 12-1). Gold mineraliza-tion resulting from dissolution of Au-bearing arsenopyrite and
