Crushing in Mineral Processing

The Compressive Strength of rocks is measured by crushing cylinder shaped (drill core) ore samples of 2″ x 2″ (51mm X 51mm). This techniques allows for a rock-to-rock relative comparison. The Bond’ Crushing Work Index is common to calculate the power needed to crush rocks from a given F80 size to a resulted P80 product size.

Crushing of Ores and Rocks in Mineral Processing

In minerallurgy, crushing is the first mechanical step in the comminution process. It allows reducing the mined ore size (up to 1 meter), until an acceptable size to undergo downstream treatment. Therefore, it places in the exit of the Mine.

Most ores, however, are made up of hard, tough rock masses that must be crushed before the valuable minerals can be released. In order to produce a crushed material suitable for use as mill feed (100 percent of the pieces must be less than 10 to 14 millimetres, or 0.4 to 0.6 inch, in diameter), crushing

May 01, 2016 Crushing is an important step in the complex process of mineral processing (Fig. 1). In open pit mines, rock chunks with edge lengths of 2 m have to be processed. In underground mines, the biggest chunk sizes are about 0.5 m. Crushers have the task of reducing the ore rock to particle sizes in the millimetre range for subsequent grinding.

Mineral processing Wikipedia

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

The goal of comminution is to crush the ore into small particles that contain only one mineral. Dry crushing ore to ~1-5 mm particles is carried out on crude ore by compression and impact force.

Pre-concentration at crushing sizes for low-grade ores

Mineral processing of low-grade ores requires high processing flow rates. Pre-concentration is a clever technological solution for this challenge because the rejection of barren rock, in the early stages of the processing flowsheet, leads to increasing the head grade of the concentration plant and reducing the corresponding input flow rate.
