Understanding the SAG Mill in Copper Ore Mining Process
A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...
Mine operating costs and the potential impacts of energy and …
Energy costs typically comprise one of the largest ongoing costs of mining operations, of which 70% is devoted to the comminution of the ore (Norgate and Jahanshahi, 2010). Furthermore, the most significant energy cost occurs in the grinding circuit of the Milling section, where up to 97% of the energy cost is incurred (Ballantyne …
cost of ball milling machine
The cost of a ball milling machine can vary depending on several factors, including the size of the machine, the materials it is made from, and the features it includes.
Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.
Trends in the mining industry
The breakthrough came in 2006 at the Cerro Verde copper ore project (Fig. 8) in Peru. By 2014, a total of 12 HPGRs had been supplied there, completely replacing an SAG concept. The comparison with a conventional grinding circuit with SAGs and ball mills returns a 21 % lower energy demand and annual operating cost savings of almost 15 mill.

Basic Ball Mill Grinding Circuit
The speed of mills depends upon their diameter; a ball-mill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times. Tube-mills run at a revolution or two faster (see Fig. 117). Some ores require much finer grinding than others to liberate the minerals, and this increases the milling cost. Ball Mill Product Classifying

Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

How is mill used in the copper ore mining process?
The ball mill is rotated, causing the balls to cascade and grind the ore. The finely ground ore is then fed into a flotation cell, which separates the copper from the rest of the material in the ore.
SAG Mill Testing
The SAGDesign test was developed by the SAGDesign Consulting Group (Starkey, Hindstrom & Nadasdy, 2006) and consists of a batch grinding test conducted in a 0.488m diameter SAG mill.
