froth flotation chemistry

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Jul 08, 2019· Concise Inorganic Chemistry by J. D. Lee claims the process of froth floatation can also be applied to non-sulfide ores such as Malachite ($ce{CuCO3.Cu(OH)2}$) and Anglesite ($ce{PbSO4}$) by using $ce{Na2S}$ as an activator. The coatings formed are $ce{CuS}$ and $ce{PbS}$ respectively.

Oct 12, 2016· Here potassium ethyl xanthate acts as a collector. $ce{KCN}$ and $ce{NaOH}$ depress the floatation property of $ce{ZnS}$ and $ce{FeS2}$ particles. Thus, only $ce{PbS}$ particles go into the froth. Now copper sulphate is added to the mixture which activates floating character of $ce{ZnS}$ and this time only $ce{ZnS}$ comes along with froth.

Froth flotation was invented in the early 1900s in Australia by C.V. Potter and around the same time by G.D. Deprat. The process was adapted and applied to a wide variety of materials to be separated. In the 1960s the flotation technique was adapted for deinking recycled paper.

FLOTATION is a physico-chemical separation process that utilizes the difference in the surface properties of the valuable and gangue minerals. FROTH FLOTATION involves three different phases- solid (fine ore powder), liquid (water) and froth. The process of separation of mineral includes three important mechanisms : 1.

Jan 20, 2021· The principles of froth flotation are a complex combination of the laws of surface chemistry, colloidal chemistry, crystallography, and physics, which even after 50 years are not clearly understood. Its results are obtained by specific chemical reagents and the control of chemical conditions.

Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).

Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation.
