Selection oof Comminution Circuits for Improved Efficiency

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...

Jan 01, 2016· In general, comminution considerations for gold milling typically do not differ substantially from those for base metal or other comminution circuits. Also, an increasing portion of gold production comes along with base metals. Many significant gold mining companies, for example, have one or more copper–gold properties in their portfolio.

It is determined by measuring the core recovery percentage of core chunks that are greater than 100 mm in length. Core that is not hard or sound should not be counted even if they are 100 mm in length. RQD was introduced for use with core diameters of 54.7 mm (NX-size core). It is a leading indicator for low-quality rock zones.

HPGR High Pressure Grinding Rolls

Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

How to ensure energy efficiency in mining

The comminution process, which includes both crushing and grinding, is one of the world's most energy-intensive industrial processes. Comminution uses at least 3% of total global electricity production, and according to the Coalition for Energy Efficient Comminution (CEEC), it accounts, on average, for more than 50% of a mine's energy consumption and 10% of total production costs.
