The two main functions of a mill liner consist in protecting the mill shell against wear and in transmitting the energy of the mill motor to the grinding charge to carry out the required size reduction in the most efficient way. For a mill liner, the design as well as the liner material are to be considered. The required movement of the mill charge to carry out effi-

"Mine operating costs and the potential impacts of energy and grinding" highlights that savings in milling costs will significantly affect total mine operating costs. The paper shows that energy costs typically comprise one of the largest on-going costs of mining operations, of which 70% is devoted to the comminution of the ore.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

The overall relative operating costs were found to be in the ratios between (43:43:14) and (45:45:10) (Mine:Mill:G & A). A treatment of potential unit operations and innovative technologies is provided at the conclusion of the paper, including coarse particle recovery by flotation and novel grinding technologies.
Traditionally, the lowest operating cost was achieved by multi-stage, fully autogenous grinding since this eliminated the steel grinding media costs which may represent up to 50% of the grinding cost.
