The response of feldspar flotation to tallow diamine dioleate collector in the presence of sulfuric acid is studied using, batch flotation experiments. Application of this non- hydrofluoric acid (non-HF) reagent system in the flotation of mineralogically and chemically different feldspar ores is compared with that of the conventional hydrofluoric …
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, …
BSE images of the gouge (35% K-feldspar, 32% plagioclase, 28% quartz, 5% mica; particle size <=88μ m) deformed in rotary frictional sliding at room temperature and 25MPa normal stress were studied at 250x, 500x, and 1000x magnification. We quantified changes in size and shape of the gouge particles as a whole and quartz and feldspar particles …
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. ...

Comminution and de-sliming processes removed about 30% of iron content into -38 μm fraction. The attrition process removed only about 6% of iron content. ... Potash feldspar is the major constituents of …
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 …
In this study, the behaviors of quartz and feldspar comminution in the same grinding conditio ns are investigated that firstly Bond Grinding test and then analyzed using the kinetic model. Results ...
An investigation of the factors affecting the performance of electrical comminution was carried out with two major approaches: an experimental study and a numerical study. The aim of the experimental study was to identify the factors that may affect the electrical comminution performance in terms of particle weakening and …
Key ore characteristics to be profiled by robust mineralogicalmetallurgical characterization programs impacting HPGR performance and throughput are as follows: • • • • • • • QKP (quartz-K-feldspar-plagioclase) concentration Ore moisture Ore density HPGR feed size distribution Compressive strength ATWAL® Wear Index (Patzelt et al ...

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) …
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.

As an example, for a covalent compound such as K-feldspar the solubilization mechanism involves rearrangements of chemical bonds in the Si-O-Al framework, and is not well defined due to ...
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 …
From a mineral processing perspective, zones of intense feldspar alteration can affect the comminution process, and in some cases, may lead to early modifications of ball and SAG mill design, e.g. Cadia Valley, New South Wales (Keeney 2010; Bonnici 2012). Thus, early identification of feldspathic ore and waste rock can improve the long …
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.
