Gold extraction

Mill Sizing. The ore throughput rate of a mill is largely dependent on the mining production rate. Generally, it closely related to the mining rate of ore only. The goal is to have the mill operating with little to no downtime, without having to stockpile massive quantities of ore for a feed supply.

Workers used pickaxes and pry bars to get the ore out of the ground. After digging the ore, they tried to remove as much waste, including clay and soil, as possible from the ore. One method was to flat the ore, or roll cast-iron, horse-drawn breakers over the ore. In the nineteenth century workers also often washed the ore to separate waste.
