• Gold mineralization occurred in the subduction stage of Early Paleozoic Proto-Tethys ocean, and its age is limited between 454 Ma 439 Ma. H-O-S-Pb-Hf isotopes indicate a magmatic-hydrothermal source, closely related to monzogranites. The Heihaibei gold deposit may instead be classified as granitic intrusion-related deposit. newly discovered southern part Eastern Kunlun Orogenic Belt. Its most...

OBJECTIVES Gold miners use mercury to extract gold from ore adding liquid mercury to the milled gold-containing ore. This results in a mercury-gold compound, called amalgam. Miners smelt this amalgam to obtain gold, vaporizing it and finally inhaling the toxic mercury fumes. The objective was to merge and analyze data from different projects, to identify typical signs and symptoms of chronic in...

Abstract Gold-containing ore processing technology has been developed by using chemical, X-ray phase, mineralogical, fluorescence analyses. The results of experiments on the gold recovery from a concentrate with particle size 10 and 4 µm are presented, including options for direct cyanidation without preliminary oxygen oxidation, as well use oxidation Trichloroisocyanuric acid (TCCA) Sulfanol s...
