Gold-rich pyrite formed by dissolution of dolomite and sulfidation of its contained Fe. Where dissolution and replacement were complete, ore-stage pyrite and other insoluble minerals were all that remained. Locally, these minerals accumulated as internal sediments in dissolution cavities to form ore with gold grades >400 g/t.

Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines.

Gold smelting is an essential process in the journey from raw material to pure gold. Smelting is the process of heating and melting the gold concentrate to separate it from other impurities and achieve a higher level of purity. This crucial step plays a significant role in transforming the gold concentrate into a more refined and usable form.

Gold ore basically looks like — well — a rock. In order to extract pure gold, refiners put the ore through a multi-step process. In the first step, the gold ore is crushed and ground into a fine powder. This step increases the surface area of the ore, allowing for better extraction of the gold particles. The next step is to separate the ...
