Depending on the mineralogy properties of the ore, physical separation can occur at crushing sizes through optical sorting, dense media separation (DMS), jigging and screening, or at fine crushing and grinding sizes by gravity separation and froth flotation (Abols and Grady, 2008; Gupta and Yan, 2016; Wills, 1992). Typically, separation at ...

Spodumene ores are typically consolidated from ore comprising 1–1.5% Li20 to a concentrate of about 6–6.5% Li20. To achieve this, the ore passes through a typical concentrator-type plant, flowing from crushing and grinding, to gravity separation and DMS, to flotation, and then to the final dewatering of the concentrate. While

The wet grinding circuits in most mills produce pulps of from 40% to 60% solids which are ready for leaching. In a few cases, where grinding is more difficult and the classifiers or cyclones overflow at a more dilute pulp density, it is necessary to thicken ahead of leaching. LEACHING The extraction of uranium from ore is accomplished
