Flotation is a complex process that occurs in solid–liquid-gas multiphase systems, and its
main factors include the minerals, separation medium, as well as various flotation reagents …

Biochar is a solid product generated during the thermochemical processes of biomass, such
as pyrolysis, hydrothermal carbonization, torrefaction, and gasification. As a material …

The application of biochar to soils contaminated with potentially toxic elements (PTEs) has
received particular attention due to its ability to reduce PTE uptake by the plants. Therefore …

The use of low-cost substances such as biochar could be a sustainable approach to reduce
the mobility, accumulation, and toxic impact of heavy metals in crop systems. This study …

In the present work an intense bibliographic search is developed, with updated information
on the microscopic fundamentals that govern the behavior of flotation operations of …

In this study, sodium alginate (SA) was used as a selective depressant, combined with
potassium permanganate oxidizing pretreatment, which will benefit the separation of …

Arsenopyrite is a hazardous substance exist in copper concentrate, thus causing serious
environmental pollution during the smelting process. However, the selective depression of …

This paper investigated the effects of potassium ferrate (PF) on the flotation performances of
chalcopyrite and galena. The flotation results showed that PF obviously depressed galena …

The activation properties of ammonium oxalate on the flotation of pyrite and arsenopyrite in
the lime system were studied in this work. Single mineral flotation tests showed that the …

Pyrite is often found alongside other sulfide minerals and is typically suppressed by lime
during industrial flotation to selectively enrich with other valuable minerals. Given the …
