Size reduction by crushing has a size limitation for the final products. If further reduction is required, below 5- 20mm, grinding processes should be used. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction and attrition. The two main objectives for a grinding process are:

Crushing Equipment for Gold Mine Mining Plant
Among all the stages, the crushing and screening are two main stages for the process flowchart of gold mining. In the first place, large gold-bearing stones are crushed by crushing equipment, and then the crushed gold-bearing stones will enter the grinding mill through the vibrating screen.

Ore Processing Challenges in Gold Operation Grinding Circuits
In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput. This is essential for driving the overall efficiency of the operation because the process of grinding and crushing ore — known as comminution — is on average the highest energy step in mining.

Gold processing 101
Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and. Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.

Ore processing – Waihi Gold
Grinding and sizing. Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding

The mining process – an overview for students – Waihi Gold
The first part of the mining process involves finding the minerals. Exploration for gold and silver for modern mining in Waihi began in the 1970s and prospecting continued into the 1980s. Diamond drills bored into the ground at an angle of 45° and collected core samples from various depths. Approximately 13,000 metres of drilling was completed.
