There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:

Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.

For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.
