crushing and grinding of the ore; addition of process water (generally decanted from the tailings pond) to form a slurry; addition of lime to the ore, and cyanide solution to the slurry, . 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.
Ore is recovered from the ROM bin by apron feeder, fed to a jaw crusher and then conveyed directly to a single mill. > The mill is configured as a SAG mill and operates in closed circuit with hydrocyclones. > A centrifugal gravity concentrator treats a bleed of the hydrocyclone underflow to recover coarse gold.
MILLING. The Boroo flowsheet for ore processing is a standard layout that consists of crushing, grinding, gravity concentration, cyanide leaching and gold . Cyclones divide the ore into two streams, with the cyclone underflow reporting to the ball mill and the cyclone overflow reporting to the carbon in pulp (“CIP”) circuit.
For such Mine- to-Mill projects, PTI's methodology is termed Process Integration & Optimisation (PIO). Ahafo operate a SAG mill, ball mill and pebble crusher (SABC) . oxide ore is fed to the mill to balance the head grade and recovery in the leach circuit. . product is thickened and pumped as feed to carbon-in-leach tanks.
