Grindin' at the Mill - investigating bottleneck in ...

Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade (~0.5% Ni) and inherently low nickel recoveries due to the mineralogical makeup of the ore. The Nickel West Mt Keith Concentrator (NMK) has 2 parallel grinding modules consisting of one SAG Mill and one BALL Mill per module. A third ball mill ...

What is the difference between a SAG mill and ball mill?

The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries.

What’s the difference of Ball mill, SAG mill, AG mill?

A Sag mill is most often used in the mining fields, particularly in the mining of precious metals such as gold, copper, silver, and nickel. The sag mill serves in the line of industrial mining equipment designed to process, crush, separate, or locate precious metals from mined coal. The Sag mill is one of the large mining equipment pieces, and often requires mining equipment repair and ...

Difference Between Sag Mill vs Ball Mill - mech4study

12/10/2017· The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of the drum uses the lifting plates. These plates inside the drum are responsible for picking the grinding material up to fall down again throughout the rotations. Repeated collisions between the steel balls and raw materials (ore ...

Selection of Comminution Circuits for Improved Efficiency

Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A$1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 40%. Autogenous milling is typically practiced in association with

Nova Nickel-Copper Project, Balladonia - Mining …

The crushed ore will be ground in an open circuit SAG mill followed by a ball mill in closed circuit with hydrocyclones. The material will then pass through flotation, resulting in the production of separate copper and nickel concentrates. The final tailings will be transported either to the high-density polyethylene (HDPE) plastic-lined ...

Nova Nickel Project - GR Engineering

Coarse ore is ground in a two stage grinding circuit that comprises a SAG and ball mill. The ore/slurry from the grinding circuit is classified via the mill cyclones and the cyclone overflow undergoes differential flotation. The nickel and copper flotation circuits have dedicated regrind, cleaning and re-cleaning processes to optimise metal recovery in each circuit. Plant tailings are pumped ...
