Answer to Question #256061 in Chemical Engineering for Thando

Question

The three major steps involved in Mineral Processing namely: Crushing, grinding and flotation. Please discuss the importance of each during mineral processing. 

 Discuss the importance of sustainability in mineral processing industry or business.

Answer 1

Crushing is the process of breaking down materials into smaller pieces so that they can be treated further. Industrial crushing equipment can be highly beneficial in a range of businesses in addition to the chemical industry.

In engineering, grinding can be used for the following purposes: an increase in a solid's surface area

Flotation is a technique for extracting minerals from gangue by exploiting differences in hydrophobicity. Prior to further refinement, the flotation process is used to separate a wide range of sulfides, carbonates, and oxides.

Environmental responsibility is critical to mining and industry's long-term sustainability. Several pieces of legislation have been adopted to address the environmental implications of mining and thereby create an enabling environment for long-term growth (SD).
