Dry-steam (superheated steam with little or no liquid) geothermal resources can be directly coupled to a steam turbine. Wet-steam or hot-water resources that are under high pressure currently use flash systems to generate steam suitable for input to the turbine. Dual-flash, binary-cycle, and flow systems are also being developed to make lower-temperature sources …

01-10-2022 · Oct 1 2022. The beneficiation process can be defined as a treatment process of ore which results in a more concentrated form of the product. It is often used in the preparation of iron ore for smelting. This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained
