· Mineral locking ratio or category of the particular mineral was calculated using the total area percent of the minerals, particle size, and the associated mineral of interest []. The minerals were categorized based on their area percent of surface exposure (x): liberated (x ≥ 90%), high middling (60 ≤ x < 90%), low middling (30 ≤ x < 60%), and

· The economic advantage of sulphide ores lies in their amenability to concentration through flotation – a process whereby crushed ore is mixed with water to create a slurry. When agitated, chemicals are introduced which cause the sulphide minerals to become hydrophobic (water-repelling) and attach to air bubbles.

· Therefore, pyrite is a common by-product with low economic value in most sulfide mineral processing plants. The feasibility of utilizing pyrite to degrade other organic contaminants in aqueous solution has been previously studied and established ( Guo et al., 2021 , Pham and Chihiro, 2019 , Pham et al., 2008 ).

· Sulfide minerals are the key metal-bearing constituents of many of our most important ore deposit types. There is a wide range of ore deposit types because S is highly mobile in aqueous fluids and magmas. Various sulfide ore deposit types fall under the broad headings of magmatic, magmatic-hydrothermal, and hydrothermal ore deposits.

· In some Ni-Cu sulphide ores with low sulphide mineral content, but rich in precious metal levels, processing requires activation rather than depression. Recent work suggests that the ammoniacal solution of copper sulphate is more effective on pentlandite than the copper sulphate itself in the alkaline range [ 54 ].

· The effects of mineral processing wastewater on sulfide minerals were investigated by flotation, infrared spectrometry and electrochemistry test. The results show that lead-concentrate water can improve the flotation of galena, while the sulfur-concentrate water has negative effect on flotation of galena compared with distilled water.

Flotation is still the most widely used and researched method for separating minerals, and is the only method which can be used to produce separate concentrates from complex sulphide ores. However, its performance on these 'modern' ores is poor, and it is in this area particularly that chemical methods will increasingly be integrated into plant circuits.

· Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings.
