DOI: 10.1016/j.jmrt.2021.01.086
Abstract: Abstract Mineral separation by flotation is a water-intensive process; thus, recycling and reusing the process-water have essential environmental and financial impacts for ore beneficiation plants. The recycled water contains different ions, which affect flotation responses.… read more here.

DOI: 10.1016/j.mineng.2019.105890
Abstract: Abstract Ethyl xanthate (EX) is a widely used collector in the flotation of sulfide minerals. However, it also has the disadvantages of low selectivity and harm to human health. Screening and/or designing more selective and… read more here.

DOI: 10.1016/j.mineng.2021.106803
Abstract: Abstract Chalcopyrite (CuFeS2) is one of the main copper minerals, and is always found associated with pyrite (FeS2). To obtain a satisfactory Cu concentration, the undesirable pyrite component must be discharged into tailings. O-isopropyl-N-ethyl thionocarbamate… read more here.

DOI: 10.1016/j.molliq.2019.111774
Abstract: Abstract Inorganic depressants are commonly used in the flotation separation of chalcopyrite from pyrite, but they adversely affect the environment. The use of degradable and environmentally friendly depressants is therefore important. In this work, lactic… read more here.

DOI: 10.1016/j.seppur.2020.116650
Abstract: Abstract In the flotation process of copper sulfide, traditional inorganic depressants used for pyrite often cause environmental problems and difficulty in treatment of the tailings and waste water. Therefore, it is necessary to explore non-polluting… read more here.
