Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the effective impact between the ball and the material.

Before the mine was closed in 2002, high grade ore was processed in a conventional mill and leach plant. Low grade ore was heap leached. The recovery plant had a design capacity of 3,175t/d, comprised of 2,358t of lowgrade ore crushed in two stages to 19mm and 816t of highgrade ore crushed in three stages to 13mm for milling.

Following prolonged washing to neutral reaction, the ore was cyanided, using solutions carrying 1 kilogram per metric ton KCN and to kilogram CaO. The mill had a capacity of about 6500 tons, per month, and about 90 per cent of the gold and 84 per cent of the silver in the ore were recovered by the process described.

Lime reagent dosing methods in gold processing are typically dependent on the extent of acid consuming reactions and the accuracy of pH control required. The simplest dosing format is where dry quicklime (of particle size < 25 mm) is directly applied to ore on a conveyorbelt ball mill feed via a dosing screw attached to a lime silo.

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
