the basic ore slurry can be combined with a solution of sodium cyanide or potassium cyanide; many operations use calcium cyanide, which is more cost effective. to prevent the creation of toxic hydrogen cyanide during processing, slaked lime ( calcium hydroxide ) or soda ( sodium hydroxide ) is added to the extracting solution to ensure that the acidity during cyanidation is maintained over ph 10.5 - strongly,chem-guide: sodium: occurrence, extraction from downs,rock salt (nacl) is the major source of sodium. potassium occurs mainly as deposits of kcl (sylvite), which is a mixture of kcl and nacl (sylvinite) and double salt kcl.mgcl 2.6h 2 o (carnallite). rubidium and cesium are obtained as a by-product of lithium processing. francium being radioactive does not occur appreciably in nature. ores of sodium

overview introduction to extraction of metals: metallurgy,the process of extracting a metal in pure form from its ore is known as metallurgy. the process of treatment depends on upon the nature of the ore, impurities, and the metal.it is reacts to concentration or benefaction of the ore,includes the crushing and grinding of the ore,gravity separation or levigation, magnetic separation, froth,aqueous alteration of potassium-bearing aluminosilicate,despite its simplicity, this approach has not yet been successfully implemented in mainstream agriculture, possibly due to the slow rate of potassium release from the majority of tested minerals.1,9–11,19 the design of chemical processing to extract potassium and aluminium from earth-abundant k-bearing silicates is also a
various mineral processing methods are used, often in conjunction with one another, to extract the ore from its rock encasement. comminution, hydrometallurgy, and pyrometallurgy are used to extract the gold. comminution is often one of the first steps in gold extraction. extractors break apart the hard rock containing the ore.,the extraction of potassium from k-feldspar ore by low,the low temperature molten salt method was used to extract potassium from k-feldspar ore, and some related factors including mass ratio between nano 3, naoh, h 2 o and k-feldspar ore, particle size of k-feldspar ore, reaction temperature and time were investigated, respectively. in addition, the optimum condition for this method was determined by a series of condition experiments.
the method used to extract metals from the ore in which they are found depends on their reactivity e.g. reactive metals like potassium is extracted by electrolysis. thus the method of extraction of a metal from its ore depends on the metal's position in the reactivity series. answer verified by toppr.,why is the potassium extracted from potassium chloride,the method used to extract metals from the ore in which they are found depends on their reactivity e.g. reactive metals like potassium is extracted by electrolysis. thus the method of extraction of a metal from its ore depends on the metal's position in the reactivity series.
