Key:Separate the scheelite and wolframite from the symbiotic polymetallic ores. Tungsten Extraction Process: √ Bulk flotation of sulfide ore - bulk flotation of wolframite and scheelite - heating and separation of scheelite - strong magnetic separation of scheelite tailings - gravity separation of wolframite;
Both the early scheelite and wolframite (type I) display significantly negative Eu anomalies and have high REE, Nb and Ta contents, suggesting that the initial ore-forming fluids were of magmatic

Scheelite is a calcium tungstate mineral that is commonly found in various geological environments. It is an important ore of tungsten, which is a metal known for its high melting point, density, and strength. Scheelite is named after Carl Wilhelm Scheele, a Swedish chemist who discovered tungsten in 1781. The mineral is typically found in […]
