In order to produce RA with predictable grading curve, it is better to process debris in two crushing stages, at least. It may be possible to consider a tertiary crushing stage and further, which would undoubtedly produce better quality coarse RA (i.e. less adhered mortar and with a rounder shape). However, concrete produced with RA subjected to a tertiary crushing stage may show only slightly better performance than that made with RA from a secondary crushing stage (Gokce etal., 2011; Nagataki etal., 2004). Furthermore, more crushing stages would yield products with decreasing particle sizes, which contradicts the mainstream use of RA (i.e. coarser RA fractions are preferred, regardless of the application). These factors should be taken into account when producing RA as, from an economical and environmental point of view, it means that relatively good quality materials can be produced with lower energy consumption and with a higher proportion of coarse aggregates, if the number of crushing stages is prudently reduced

Compound cone crusher (VSC series cone crusher) can crush materials of over medium hardness. It is mainly used in mining, chemical industry, road and bridge construction, building, etc. As for VSC series cone crusher, there are four crushing cavities (coarse, medium, fine and superfine) to choose. Compared with the same type, VSC series cone crusher, whose combination of crushing frequency and eccentricity is the best, can make materials have higher comminution degree and higher yield. In addition, VSC series cone crusher's enhanced laminating crushing effect on material particles makes the cubic shape of crushed materials better, which increases the selling point

In-situ mining (discussed in more detail later in this chapter) has been remarkably successful for several metallic and nonmetallic deposits. The application of this technique to the secondary recovery of mineral resources is another area for research. Extensive trials on in-situ gasification of coal have been conducted by a number of agencies worldwide, including DOE and the former USBM. In-situ mining has also been attempted for retorting oil shale. The potential benefits of the in-situ gasification of energy resources include reduction of mine development and mining and more efficient use of resources that are otherwise not economical to mine (Avasthi and Singleton, 1983). However, substantial technical problems, including such environmental issues as groundwater contamination, must first be addressed

The invention of industrial air cooling and air quality control systems saw gold mines reach unprecedented depths the deepest being 3 900 metres. This method is accompanied by chemical beneficiation, where chemicals, such as cyanide, or activated carbon are added to rough ore and processed sometimes with heat, water, agitation, electro-winning etc. Modern gold beneficiation methods can produce gold of 99.9999% purity. Making the refining process more thorough and economically viable, some projects facilitate the re-processing of 1.7 billion tonnes of gold tailings to refine a further 15 million ounces of gold

In magnetic separation, a higher quality pre-concentrate at constant yield was achieved. Both of these effects can be attributed to the same two factors: the generation of more fines and the generation of microcracks. The amount of < 150 (im material produced in the HPGR grinding stage was twice as high as what cone crushing would have produced
