A considerable difference exists between the flotation separation of artificial minerals and real low-grade ores processing where selectivity would be the main issue. Nanobubble-assisted (NB) flotation investigations have been mostly examined with pure materials and a narrow particle size range, less on complex sulfide ores.
Flotation. According to the difference in physicochemical properties of mineral particle surfaces, flotation is the method that selectively enriches the target minerals in the pulp at the gas-liquid interface and separates them from the pulp, thus realizing the mineral separation. It is also known as floating separation.
The flotation circuit for a polymetallic ore usually utilizes fractional flotation with the generation of a bulk concentrate and its subsequent separation, fractional flotation using selective flotation, or a combination of both strategies if three or more concentrates are produced (Frías et al., 2008). Here the concept of fractional ...
It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg …
The lepidolite ore used in flotation separation tests was got from Yichun Tantalum & Niobium Mine in China. The mineralogical analysis of the lepidolite ore shows that the main components of the ore were largely 27.83% lepidolite, 34.59% albite, 17.04% quartz, 7.15% sericite, 5.23% potassium feldspar, 5.06% kaolinite, 1.37% pyrite, 1.04% ...
An important point to consider in Fenton reactions is the H 2 O 2 no react in wastewater treatment for internal reuse because it could oxidize the ore's surface interfering with the flotation separation performance [10], [129], [130]. The utilization of heterogeneous catalysts can still be an alternative that can require less oxidant ...
