Coagulation and flocculation behavior of fines in foid-bearing rock processing plant (FRPP) wastewater at alkaline environment

Preparation and performance evaluation of hybrid polymer flocculants (PAC‐PAM), and comparison experiments with other flocculants

“…4,5 In addition, in recent decades, with the rapid development of world industry, the disposal of various industrial wastewater has brought greater pressure to the use of freshwater resources, [6][7][8] and the treatment of sewage is the focus. [9][10][11] According to the principle, the existing sewage treatment methods can be divided into the physical method, chemical method and biodegradation method. [12][13][14] Among them, the physical method is mainly for suspended solids in sewage, the chemical method is mainly for colloidal particles and soluble substances in sewage, and the biodegradation method mainly relies on the degradation of microorganisms to purify sewage.…”

“…Relevant reports point out that the water consumption of the world's population is increasing at a rate of 1% every year, and half of the world's population lives in water shortage areas 4,5 . In addition, in recent decades, with the rapid development of world industry, the disposal of various industrial wastewater has brought greater pressure to the use of freshwater resources, 6–8 and the treatment of sewage is the focus 9–11 . According to the principle, the existing sewage treatment methods can be divided into the physical method, chemical method and biodegradation method 12–14 .…”

Improvement Effect of FeSO4·7H2O on Flotation Separation of Scheelite from Fluorite

“…The depressant mixture is a good choice for this specific goal. To enhance the separation efficiency, a mixture of water glass with metal ions (such as Al 3+ , Fe 2+ , Pb 2+ , and Ca 2+ ) have been used in scheelite flotation. − The depressant effect of the joint addition of SS and other salts was first studied by Belash, and a number of studies have since been done. − The original study indicated that these ions could promote the depression capability of water glass in scheelite flotation systems. Oliveira and Sampaio first used FeSO 4 ·7H 2 O as a depressant in scheelite flotation .…”
