Method Of Ore Scrubbing

When the ore contains selenium it will also be liberated in the roasting/smelting process along with the mercury. The selenium will be in the amorphous state which will readily combine with mercury to form HgSe. Mercury in this form will be easily removed from the gas in the scrubbing and wet electrostatic precipitation stages.

Run-of-mine ore is dry-crushed and screened in a two-stage circuit before being slurried in a saline solution together with the fines prior to pumping to a sizing screen distributor. Mill feed is then de-slimed in a circuit of three scrubbing tanks

Feb 29, 2016· The ore body formation affects the mining method and the sequence of extracting different zones so that the beneficiation process can be effective. Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process.,Some design includes a scrubbing,

A separation process is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one product mixture of the separation is enriched in one or more of the source mixture's constituents. In some cases, a separation may fully divide the mixture into pure constituents.

The particle-size distribution (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or a mathematical function that defines the relative amount, typically by mass, of particles present according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution.
