Handbook of Flotation Reagents: Chemistry, thought and Practice is a condensed kind of the elemental wisdom of chemical reagents generic in flotation and is addressed to the researchers and plant metallurgists who hire those reagents. This ebook contains 3 particular components: half 1 offers special description of the chemistry utilized in mineral processing undefined; half 2 describes theoretical facets of the motion of flotation reagents, whereas half three presents info at the use of reagents in over a hundred working vegetation treating Cu, Cu/Zn, Cu/Pb, Zn, Pb/Zn/Ag, Cu/Ni and Ni ores.
- Looks on the theoretical points of flotation reagents
- Examines the sensible points of utilizing chemical reagents in working plants
- Provides directions for researchers and engineers desirous about approach layout and development

Thermal treatment (decapitation) is sometimes used for concentration of spodumene ores. The ore is heated to 95–1000 °C, where the spodumene is converted from α to β form in which case spodumene is transferred to powder form and is separated from other minerals either by screening or by air classification. 5% FeO. 1 Flotation properties of spodumene Flotation properties and selection of flotation methods very much depends on the type of gangue minerals present in the ore. , iron). Over the years extensive research work has been conducted on various ore types.
Pure mineral is attached but not decomposed by acid. The interlayer potassium is capable of ion exchange which as with other mica frequently occurs with iron salts. This can lead to anionic activation Handbook of Flotation Reagents: Chemistry, Theory and Practice. V.

Petalite: This is insoluble in acid and is a relatively stable mineral.
3 Flow sheet for beneficiation of petalite from complex ores using flotation. 1 Bernic Lake—Manitoba, Canada The Bernic Lake ore is relatively complex and variable within the ore body. The main minerals include quartz, feldspars, microcline, albite, and lepidolite. Major lithium minerals are spodumene with some amblygonite. The amblygonite represents a problem in recovery of spodumene as this mineral contains phosphorus, which is an impurity in production of high-grade spodumene. Initial development work started in 1978, which included pilot plant testing.
