Generally, application of the hydrolyzed starch increases the capacity and throughput of mineral ores during the grinding stage in mining processes, particularly in recovery of mineral fines from ore. This will benefit operations by decreasing downtime and moving more ore through the comminution process in shorter time periods.

For some minerals, this induced mechanochemistry can enhance recovery in flotation [37]. However, in fine and ultrafine grinding for ore liberation, wet grinding dominates due to the greater efficiency, and because subsequent separation processes tend to require wet operation, making the advantages of dry milling in terms of water usage redundant.

Chromite ore processing residue (COPR), derived from the socalled highlime processing of chromite ore, contains a significant fraction of a leachable Cr(VI) which is harmful to human being and other organisms. In recent years, the concern over environmental pollution from the waste residue containing Cr(VI) has become a major problem for the chromium chemical industry.

Grinding is an indispensable step in mineral processing to reduce particles' size and liberate minerals before they are subjected to further separation processes. Grinding is characterized by high energy consumption and low energy efficiency (~ 1%) (Cheng et al. 2019; Liu et al. 1989; NapierMunn 2015).
