Sluice design can lead to higher gold recovery if the force of the water traveling through the sluice is decreased. A series of rifles can help break the flow to improve recovery. A zig zag sluice also achieves this by creating a drop between the first and second platform that disrupts the velocity of the water as it travels down the sluice.

Definitions. "Pulp," in flotation terminology, is a freelyflowing mixture of powdered ore and water. "Pulp density," when the phrase is applied properly, indicates the specific gravity of the pulp. "Percentage of solids" means the ratio, expressed as a percentage, of the weight of the solids in a pulp to the total weight of pulp.

CIL (Carbon In Leach) is the carbon leaching method for gold extraction. Normally the CIL process can concentrate gold from g/t in ore to 2000 to 6000 g/t on carbon. CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content. It is characterized by low cost, short infrastructure construction time and few production links.

This tank is there to allow the reagents time to become well mixed with the ore and condition it for recovery. The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER.
