  • Flotation Froth an overview | ScienceDirect Topics

    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 solutionAfter carrying out a froth flotation separation, the products are as shown in Table 1 Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process1 Froth Flotation – Fundamental PrinciplesThe paper is about the froth flotation process and its application It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores Froth flotation is one of the steps which is generallyFroth flotation process and its application
