1. Introduction For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Heap leach operations, of course, have a substantially lower milling unit cost.

This study has found that in general the relative Mining and Milling costs of a given operation do not significantly differ, and generally fall within the range of 43:43:14 to 45:45:10 (Mine:Mill:G A). In addition, G A costs were found to be consistently lower than both Milling and Mining costs.

Leaching Gold Circuits. This flowsheet is the lowest in price, and can be used on what are commonly termed as "free milling" gold ores where a high percentage of the values are free and where these values are unlocked at reasonably coarse grinding. This flowsheet is often used for treating high grade pockets.

A technique has been developed that analyzes routine mill operating data to determine the key operating parameters responsible for gold losses to tails. These parameters represent the prime operating variables having a dominant effect on gold recovery. The technique quantifies these effects for the specific plant being analyzed, providing a
The most well known carboninpulp plant remains the prototype Homestake plant in Lead, South Dakota. Operating since 1973, this facility treats 2130 tonnes of ore per day averaging g gold per tonne. Homestake has also operated small silver carboninpulp plants at Creede and Cripple Creek, Colorado since 1979.

Mining law is principally regulated in terms of legislation passed by Parliament through precedent or case law from the courts; common law and customary law also regulate mining law. The Mines and Minerals Act [Chapter 21:05], and the regulations made in terms of that Act, is the principal legislation that governs mining law.

mill. Some can afford only to hand pound the grain to a coarse meal. Milling on this small scale is usually done in 3 to 20 kg batches of grain, or an amount a household requires for 1 to 14 days. In periurban or suburban areas, people often buy grain at the market and grind it to a meal at a local mill.

Step 1: Milling. When ore enters the plant from underground it first needs to be milled to reduce its size so that the gold is liberated from the host rock. South Deep's milling circuit consists of a singlestage semiautogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball ...
