Sisson Tungsten-Molybdenum Project
The conventional open-pit mining method involving drill, blast, load, and haul operations will be employed for ore extraction. The run-of-the-mine (ROM) will undergo crushing and floatation for the production of tungsten and molybdenum concentrate at an on-site ore processing plant. The tungsten ore will be further refined at an APT plant ...

Tungsten Statistics and Information | U.S. Geological Survey
Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides. Cemented carbides (also called hardmetals) are wear-resistant materials used by the metalworking, mining, and construction industries. Tungsten metal wires, electrodes, and/or contacts are used in lighting, electronic, …

Tungsten Ore Extraction Processing
Tungsten ore is a rare metal that is widely distributed and exists in almost all kinds of rocks. Due to its low content, it can only be enriched through relevant geological processes before forming ore deposits for mining. At present, more than 20 types of tungsten ore have been found in nature, among which scheelite and wolframite are …
