The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.

Some companies do not distinguish between grinding and polishing, as in the previous paragraph, but use the term lapping to mean grinding or coarse polishing with an abrasive slurry against a hard metal platen. Lapping is used in ceramography and ceramic manufacturing to produce extremely flat surfaces.
shown in Figure 2, is designed to reduce 41.5 tons/hr of gold ore from a feed range of 2-5" to 160 microns. The mined ore is fed using a Grizzly Feeder, F-101, into a Jaw Crusher, J-101, where 80% of the ore is crushed to 1.75" or smaller. The remaining 20% are recycled back into F-101 (not shown on PFD) .
Mechanism of ultrasound treatment on slurry at low temperature The essence of gold cyanidation is that gold dissolves in the alkaline cyanide solution and forms a gold cyanide complex ( Au CN 2 - ). This dissolution mechanism is essentially an electrochemical reaction process. The overall reaction is shown in Eq. (1) [36].

Particle size monitors use ultrasonic attenuation technology to provide particle size analysis of a mineral slurry stream. They can help ensure the final grind target at each instant of the process. Continuous, real-time feedback will instantly alert the plant manager to process upsets, allowing a quick reaction to lessen the impact.
Slurry Filtering & Concentrate Filtration. The purpose of a vacuum filter is "Slurry Filtering" and therefore to remove more of the water from the concentrate, this "Concentrate Filtration" is accomplished by using a vacuum.
