Overview of Extraction of Mineral/Metals with the Help

2016-12-20  Extraction of silica from geothermal fluid is termed as the cascade use of geothermal energy. Geothermal fluid contains silica which clogs tanks, pipes and other equipment as the pressure and temperature decreases during processing. So, by removing silica from the geothermal fluid, the geothermal industry will provide silica, which is a marketable by-product. Also, it will increase the hot fluid extraction from production wells. This experiment is carried out in Livermore’s mobile laboratory at the Mammoth Pacific LP geothermal power plant in Mammoth Lakes, California. The Livermore extraction process involves running a geothermal fluid through a reverse-osmosis separation process to create freshwater and concentrated brine. The freshwater is used for evaporative cooling, and the concentrated brine is pumped into a reactor where chemicals are added and silica is extracted. The silica-free brine can then be pumped through another process for extraction
