Flotation. Flotation makes use of density separation, but in a special way. Chemicals are added to change the surface properties of the valuable minerals so that air bubbles can attach to them. The minerals are mixed with water to make a slurry, almost like a watery mud. Air bubbles are blown through the slurry and the minerals attach to the ...

Potassium is one of the three basic plant nutrients along with nitrogen and phosphorus. There is no substitute for potassium compounds in agriculture; they are essential to maintain and expand food production. Potash is extracted from buried ancient evaporites by underground or solution mining. This accounts for most of the potassium produced. Another important source is brine

Jan 01, 1995  The presence of insoluble mineral components, typically clay minerals, in potash ores has always been a problem to the potash industry, particularly in the processing of low grade sylvinite ores. The insoluble slimes must be removed prior to potash flotation because of their high affinity for amine collectors used in the subsequent flotation of ...

Mineral processing - Wikipedia

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

Potash - METS Mineral Engineering Technical Services

Potash. Potash or potassium salts are produced through two primary sources; brines and evaporite deposits. The two most common and economically important potassium sources are sulfate of potash (K 2 SO 4 – SOP) and muriate of potash (KCl – MOP). Evaporite deposits are usually quite deep, and are either mined through underground mining or in-situ solution mining.
