Comminution is known to be an inefficient user of energy. This makes it the largest energy consumer in many mine sites and therefore a large component of cost. One would therefore have thought that improving comminution energy efficiency would be receiving the undivided attention of the mining industry, but this is not the case. ...

Essentially, comminution is the key for mineral beneficiation where the aim is to form mineral components into least energy consuming elements in terms of thermal, physical or chemical treatments.
The following are some of the important factors that affect the size reduction process. Hardness and Toughness Hardness is the ability of the substance to withstand pressure, and toughness is the ability of a substance to resist being fractured when pressure is applied. It is easy to break soft materials to small sizes than hard materials.

Novel interdisciplinary approaches are needed to predict the release of nutrients from agrominerals. This study presents one such approach, proposing a detailed analysis of the relationship between petrographic characteristics of twelve samples of ultrapotassic syenite (K-feldspar ore), and the leaching of potassium from their powders.
Section snippets Chemicals and materials. Spodumene crystals were obtained from a rare metal mine in koktokay (Xinjiang, China), and feldspar and quartz crystals were obtained from a spodumene mine in jiajika (Ganzizhou, Sichuan, China).The spodumene, feldspar and quartz crystals were crushed with a hammer, separately, and …

Show simple item record. Characterization of potassium agrominerals: Correlations between petrographic features, comminution and leaching of ultrapotassic syenites
The X-Ray diffraction (XRD) analysis (AXS Brooke, Germany) in Fig. 1 indicates that the dominant minerals in the ore are quartz, feldspar, and spodumene. …
on the Earth surface of high purity K-feldspar rocks such as ultrapotassic syenites make comminuted K-feldspar a material worth considering as an alternative potash fertilizer7. However, attempts in this direction have been unsuccessful thus far, presumably due to the slow leaching rate of framework potassium from K-feldspar7,43,50,51.

Flotation is widely regarded as the most effective method for separating spodumene from feldspar. The efficiency of this separation process is largely dependent on the choice of flotation reagents. In this work, an efficient collector, sodium N-oleoylsarcosinate (SNOS), was employed to achieve the separation of spodumene and …
A pegmatite ore (with the Li 2 O grade being 1.56 %) was obtained from the mines of western Sichuan, China. The XRD and multi-elemental chemical analysis results of the ore were presented in Fig. 2 and Table 2.It can be seen in Fig. 2 and Table 2 that the valuable mineral was spodumene, and the primary gauge minerals were feldspar, …

Feldspar Ore Grinding. The Rod Mill is standard for grinding feldspar ore, producing a granular product with a minimum of slime and fine size material. Grinding is always done to minus 20 mesh on account of market requirements. Feldspar this coarse will float very nicely and if liberation is obtained at this size no further grinding is necessary.

The largest consumption areas of feldspar produced in Turkey have been ceramic, glass industries, painting, welding electrodes and plastic industry. The biggest challenge in producing K-Feldspar is due to the production of glaze K-Feldspar and grinding of the K-Feldspar. This is a fact that the coming years will be even more important.

Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores. Dry recovery methods are economically limited to about 17% Al2O3. The problem in feldspar flotation is to recover slime free granular …

In a standard design of a mineral processing plant, comminution tests play a significant role [17]. A geometallurgical model of a deposit provides an image of the resource's variation, identifies the spatial geometallurgical domains of the orebody, and determines the response of the ore rocks to the beneficiation plant.
