Separation of ultra

Apr 01, 2021PEO could flocculate quartz and improve its flotation recovery into the froth product thus lowering its entrainment to the hematite concentrate (flotation tailings product). The use of PEO helped achieve a better hematite concentrate with higher grade and recovery from mixtures of ultra-fine hematite and quartz. 2. Materials2.1. Mineral samples

Role of dissolved mineral species in quartz flotation and

activated by calcium at strong alkaline pH, quartz nevertheless, reports to the concentrate with Fe when the iron ores contain siderite. It causes a poor concentrate grade and separation between quartz and iron minerals. The effect of siderite on reverse anionic flotation of quartz from hematite was studied in our previous investigations.

Reducing quartz entrainment in fine coal flotation by

Jan 01, 2019To better understand the flotation performance, coal and quartz were separated from the froth product. Fig. 4 presents the recoveries of coal and quartz as a function of PAC concentrations. As can be seen in Fig. 4(A), when SHMP was not added, the quartz recovery was 37.40% in the absence of PAC and it steadily reduced to 26.78% as PAC concentration increased to 50 mg/L.

Cu(II) and Ni(II) activation in the flotation of quartz

However, the flotation separation of fluorite from quartz using water glass is not so effective, as there is always a small amount of fine quartz (less than 10 μm) in the fluorite concentrate.

The Effect of Quartz on the Flotation of Fine

The flotation separation between fine wolframite and quartz did not work, and the grade of wolframite concentrate decreased as the size of the quartz particles reduced. The ICP and zeta potential results suggest that metal ions dissolved from wolframite changed
