To make mining efficient and effective, the raw rock and soil are typically not examined on-site. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds.
An optimal crushing process reduce the ore to a desired size more efficiently, economically and safely. The high-capacity, reliable and energy efficient crushing solutions deliver superior performance and maximized throughput also for the most demanding mining applications.
Originally designed for ore with moisture levels of around 4-6%, the NextGen 2 is processing ore with moisture up to 15-16%, and averaging between 10-12%. Ore with a higher moisture content would usually require a below water table style plant (wet plant), which has a higher cost than an above water table style plant (dry plant).

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

Lead-bearing ore is mined from underground or open pit mines. After extraction, the ore is processed by crushing, screening and milling. Domestic lead mine production for 1991 totaled 480,000 megagrams (530,000 tons) of lead in ore concentrates, a decrease of some 15,000 megagrams (16,500 tons) from 1990 production.
In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
