When ground ores are fed into the suspension, the gangue particles, having a lower density, tend to float and are removed as tailings, whereas the particles of valuable minerals, having higher density, sink and are also removed. The magnetite or ferrosilicon can be removed from the tailings by magnetic separation and recycled.

The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting. This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine.

A more specific and familiar definition is provided by Adel et al (2006): Mine to Mill (optimisation) is a holistic approach to the optimisation of mining and processing operations. It attempts to minimise energy consumption of the particle size reduction processes. The above M2M concept has an energy focus.

The operator monitors the load in the mill and the power and evaluates how they are performing together. They should trend the same. If you have more or less load in the mill, then you should be using more or less power (if the hardness of the ore is the same). If the trends diverge, then something has changed.

Autogenous and Semi-Autogenous Mills. Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media.

Processing. Our mills run the ore through ball and rod mills to reduce it to the proper size for our flotation process. Flotation separates the copper, zinc and lead. After separation, the various concentrates are dried to the consistency of a damp powder before being stored in our enclosed storage and shipping facility.
