SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along, eight-inch-diameter steel balls are added to the rocks as they tumble inside the rotating mill (semi-autogenous — gets some help from the steel balls).

2021-9-8  copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. While copper in its purest form is a very soft metal, almost any element that can be added to copper will increase its hardness. The addition of tin not only imparts strength but also results in an alloy, known as

Stirred Media Detritors (SMD) - Outotec

Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding.
