·Potash is the term generally given to potassium chloride but it is also loosely applied to the various potassium compounds used in agriculture po tassium sulfate potassium nitrate or double salts of potassium and magne sium sulfate generally langbeinite K S0 • 2MgS0 Sometimes the var 2 4 4 ious compounds are differentiated
·The correct selection of technology for processing potash ore depends on its mineralogical composition the natural size and shape of grains as well as on the amount and size of halite grains
The Process of Producing Potassium Carbonate from Potash Potassium carbonate can be produced from either natural or synthetic sources One of the most common methods for producing potassium carbonate involves using potash as a raw material The process begins with mining potash ore from underground deposits Once mined the ore is crushed and
·A new comprehensive way to extract lithium and potassium from lepidolite through calcination process with the additive of K 2 CO 3 has been proposed By using flowing water vapor the lepidolite concentrate mixed with % of K 2 CO 3 could generate acid soluble potassium aluminum silicate KAlSiO 4 and water soluble lithium/potassium
·The paper comprises the study of the enrichment process of potash ore with the addition of industrial oils I 8A I 12A I 30A to the base complex collector as an additional hydrophobizator RESULTS Comparative studies of flotation using liquid paraffins and industrial oils have shown the effectiveness of the latter Physical research methods

·Large amount of solid and liquid waste is a serious issue associated with potash mining and processing Potash ore enrichment generates solid halite waste clay salt slurry and industrial wastewater with a high content of water soluble salts The «environmentally friendly» storage of such waste is a difficult technological issue Highly
·1 Introduction Applying flotation to treat ores containing water soluble salts as pointed out by Gaudin in his monograph Gaudin 1957 was not considered until after Jeanprost 1928 showed that the flotation must be conducted in a saturated solution of such minerals sylvite KCl and halite NaCl two major components of the most
·The process of enrichment of potash ore using industrial oils as a hydrophobizing agent in the collective mixture of potassium chloride which is a composition of salts of higher aliphatic amines
·The ore transportation to the shaft will be carried out using underground conveyor belts Later an approximately 25km long overland conveyor will deliver the extracted ore to the processing plant The ore will then undergo crushing and a conventional flotation process will be employed by the plant to produce the potash concentrates
·Second potash prices are prone to volatility—for example prices spiked in 2009 and 2021 Fig 2 In 2009 potash prices spiked by ∼ 240% reaching US$682 t −1 ref 18 This was probably
