Abstract:
Based on ore examination tests in different levels and grades, the composision, mineral component, tex- ture, structure and Gold occurrence of Gold ore in Fuweng are discussed. It shows that the Fuweng Gold deposit in Ding'an is a middle scale quartz-type Gold deposit with high-sulfide. The ore body is controlled strictly by the fracture. The useful composition in the ore is multiplicity, the harmful composition is lack and the major mineral is nature Gold. The major metallic minerals and also the major Gold carrier minerals are pyrite and arsenopyrite. The nonmetallic minerals are quartz and carbonate mineral. The automorphic, hypidiomorphic and xenomorphic granular textures are the main ore textures, and vein and disseminated structures are the main ore structure. The forms of nature Gold are granular and long-granular. Gold occurs mainly in the shape of fissures, the secondly in interparticles, and inclusion Gold takes only about 16.9%. The native Gold is in microsize. The major ore type is Gold-bearing quartz type with poly-metal sulfide containing abundant bullion and much.
