Ore and quick lime added to the ore conveyor is fed to the SAG mill at a rate of 350 tph to 480 tph. The SAG mill (Morgardshammer, 8.0 m x 3.95 m, 3.8 MW, fixed speed) uses 125 mm diameter balls as grinding media at an average 10% to 12% charge volume. Water is added to the mill to keep a charge density of 60% to 85%.
In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually Ball or SAG mills. Inside these Sag/Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being ...
Semi autogenous grinding (SAG)technology, as an effective measure to reduce the capital investment and production cost, has been widely recognized. It has been widely applied in non-metal mineral processing, ferrous metal mineral processing and non-ferrous metal mineral processing, and is being popularized gradually in gold processing plant.

This provides an opportunity for economic ways to extract gold from the deposit by carrying out primary crushing and placing the material into a sag mill. A sag mill is significantly cheaper to operate and also provides a larger throughput as compared to a bore mill. This enables the company to make massive gold recoveries with a significantly ...
Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
The crushed ore produced will be separated by size to separate fine ore, from the coarse ones which will be fed back to SAG Mill for regrinding. The fine ore, will be sent to further milling, so that they are ideal for the leaching process. The ore, which is in slurry form, will be contacted with cyanide solution to dissolve its gold content.
