Source and Evolution of the Ore-Forming Fluids of Carlin
The source and evolution of ore-forming fluids is important to understand the genesis of Carlin-type gold deposit. Constraints on the source and evolution of ore fluid components by the conventional geochemical methods have long been a challenge due to the very fine-grained nature and complex textures of hydrothermal minerals in these deposits. In …

Types of ores
conversion of ore is taken place by employing oxygen or other element. This process was used to remove Sulphur or other elements such as arsenic and tellurium in the form of a volatile oxide from an ore. Ore is crushed and heated to a high temp using a strong blast of hot air. The process converts the ores to their oxides which can then be reduced.
