بيت /What Should Be Pulp Density In Flotation Of Copper
· In flotation mineral processing, the flotation machine scrapes the s with minerals, to separate the valuable minerals and gangue minerals. In this period, the pulp contains solid, liquid and gas materials. The process by which the mineral particles in the pulp adhere to the bubbles is called bubble mineralization.

· And during the froth flotation process of fine particles and the ore containing high mud, the slurry concentration should be 10% to 20%. Because the larger the particle size is, the thicker the slurry concentration should be. When the flotation density is small, the fine and muddy minerals should use a relatively thin pulp.

The results revealed that rheology, which is caused by pulp density, played a key role in flotation performance. The decline in density (from 40 wt % to 20 wt %) increased the nickel and copper recoveries from % to % and 82% to % respectively in the artificial mixture (1:1).

In mineral flotation, rheological problems have limited the efficient upgrading of lowgrade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.

· At the beginning, the density of hot water is quite high, so everything should sink, but at some point the density will have decreased to the point that the object begins to float! Insert the value of salinity and temperature at which the object began to float into water density calculator, and you should be able to estimate those densities with relatively good precision!
