Coal Processing an overview ScienceDirect Topics

But this is rather the exception and is why circuits are widely used in mineral processing, for example, rougher-cleaner-recleaner spiral circuits in iron ore processing, and the wide range of flotation circuits is evident in Chapter 12. Circuits are less common in coal processing, but the advantage can be demonstrated (Bethell and Arnold, 2002).

Tailings Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

The taconite ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. The six-digit Source Classification Code (SCC) for taconite ore processing is 3-03-023. Table 11.23-1 lists the SCCs for taconite ore processing. Taconite is a hard, banded, low-grade ore, and is

Mineral Processing Wastes Material Description User

In general, the lower the concentration or percentage of ore in the parent rock, the greater the amount of processing needed to recover the ore and the finer the particle size of the resultant tailings. Some ores, such as iron ore, are found in relatively high percentages and are fairly easy to separate.

processing and refining, comes immediately after the extraction process as shown in figure 1. In the mined material supply chain, ore concentration is the process whereby the mineral being mined is separated from mineral bearing rock, either chemically or physically. Prior to this the ore must be crushed to a size suitable for 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.
