ادامه مطلب1. Introduction. At present, more than 35% of China's gold resources (with a total amount of more than 1,000 tons) are difficult to be exploited and smelted, and about 700 tons of gold ores with high arsenic, antimony or sulfur are difficult to be directly cyanide leached (Lei et al., 2016).However, as the gradual depletion of easy-to-treat …

Repeat sampling gave an average of 240.2 g/t Au (original sample plus three repeat …
ادامه مطلبIn the northwestern margin of the Youjiang basin (NWYB) in SW China, many Carlin-like gold deposits are highly antimony (Sb)-rich, and many vein-type Sb deposits contain much Au. These deposits have similar ages, host rocks, ore-forming temperatures, ore-related alterations and ore mineral assemblages, but the Au and Sb metallogenic relations and …

ادامه مطلبThe gold is particulate within arsenopyrite grains. The RGO ore is a complex refractory gold ore. Whilst flotation and concentrate roasting, pressure oxidation (POX), and bacterial leaching (BIOX) were all studied the environmental regulators would not agree to chemically changing the arsenopyrite containing the gold.

ادامه مطلبGold grade measures the amount of gold within ore before it's processed, while gold purity refers to the percentage of gold in the final, refined product. Gold purity is either measured in fineness (the number of parts gold per 1,000 parts) or gold karats, where 24 karat gold is deemed pure.
ادامه مطلبDepending on the concentrations of gold and antimony, different categories of Au-Sb-containing sulfide ores can be distinguished: (1) ores in which gold is the main valuable component and antimony ...
ادامه مطلبBased on the data of about 2000 gold deposits and other ore (mineralized) occurrences, gold deposits in China were classified into five prediction types: gold deposits genetically related to granite–greenstone formation, gold deposits related to sedimentary formation (including the Carlin type and the metamorphosed clastic rock related vein ...
ادامه مطلبHowever, it is not clear whether the gold mineralization was genetically related to igneous activity in the Kalba gold province (Kovalev et al., 2014). The North Kostobe gold deposit is located in the Bakyrchik ore …
ادامه مطلبThe refractory gold ore with a high content of antimony (25.0–35.0% Sb, Au 30 g/t) is commonly used as an important raw material in the smelting of antimony . The melting products are antimony oxide, crude antimony, antimony matte and slag. Crude antimony can be viewed as a significantly material to enrich gold.
ادامه مطلبThe Consolidated Murchison ore contains antimony which, during gold extraction, is thought to act as an oxygen scavenger (Monhemius, 1987), while increasing both cyanide and lime consumption.

ادامه مطلبOrogenic antimony-gold deposits contribute significantly to the global antimony resource base. China's orogenic antimony-gold deposits are primarily in southern Tibet. Investigations indicate that antimony combines and migrates with sulfur hydroxides in ore-forming fluids. Previous research on fluid inclusions in orogenic antimony-gold ores …
