The zeta potential measurements of pure minerals before and after interacting with biosurfactant were carried out using the electrophoretic zeta-meter system +4.0. The suspension pH was evaluated from 3 to 11, aliquots of HCl (0.1 mol/L) and NaOH (0.1 mol/L) were used to adjust the pH and NaCl was used as indifferent electrolyte.

The beneficiation of ultrafine phosphate ScienceDirect

2012-2-1  Highlights A process which successfully beneficiates ultrafine phosphate ore. The process can treat feed with up to 80 wt% −20 μm particles. Conditioning at high wt% solids and flotation with Jameson cells. Use of de-ionised water in conditioning reduces silica activation. The process recovers at least 80% P 2 O 5 to a concentrate grade of 32% or greater P 2 O 5.

An overview of inorganic particulate matter emission from

2021-3-1  Although ultrafine and fine particles only account for a relatively small portion of the particles emitted from the combustion sources, since they have characteristics of long residence time, long distance transport and high toxic adsorption capacity they do a great harm to the environment [9,10].Medical research have shown that particles with different size have different deposition trends in

The Clay minerals mainly experience loss of pore water and little oil is generated during this period. 25 to 50% illitic beds in illite-smectite mixed-layer clay minerals correspond to major oil generating zone (RO= 0.5 to 1.0%). When more than 75%

Entrainment of Gangue Minerals in Froth Flotation

Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even

Analysis of the Sedimentation Characteristics of Ultrafine

2019-11-28  Due to continuous improvements in the beneficiation process, the size of tailings has decreased. In many mines, more than 50% of the total tailings are finer than 74 μ m. Ultrafine tailings exhibit a slow settling velocity and uneven settling, which pose new challenges to the safety and stability of tailings dams. In this paper, ultrafine iron tailings from the Makeng Iron Mine in Longyan
