feldspar, sodium sulfate, anhydrous borax, boric acid, and many other materials. The bulk supplies are received by rail car and truck, and the lesser-volume supplies are received in drums and packages. These raw materials are unloaded by a variety of methods, including drag shovels, vacuum systems, and vibrator/gravity systems.

The washing process is suitable for feldspar produced from weathered granite or feldspar placer, which mainly to remove impurities such as clay, fine mud and mica. On the one hand, it can reduce the content of Fe2O3 in feldspar ore, on the other hand, it can increase the content of potassium and sodium in feldspar ore.

Feldspar for ceramic/glass industries requires sufficiently low content of harmful colourants (Fe-, Ti-, Mn-bearing mineral phases). Hydrothermally altered albite-rich granites are increasingly used as feldspar raw material nowadays; however, they are often marked by increased content of colourants, which must be removed during the processing of feldspar ore.

Metallurgical Content. 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.

Conventional open-pit mining methods including removal of overburden, drilling and blasting, loading, and transport by trucks are used to mine ores containing feldspar. A froth flotation process is used for most feldspar ore beneficiation. Figure 2-1 shows a process flow diagram of the flotation process. The

5.2 Chemical Weathering. Chemical weathering results from chemical changes to minerals that become unstable when they are exposed to surface conditions. The kinds of changes that take place are highly specific to the mineral and the environmental conditions. Some minerals, like quartz, are virtually unaffected by chemical weathering, while ...

The pulverization process of the feldspar mine includes crushing and grinding. The pulverization of feldspar is on the one hand to meet the particle size requirements of the final product, and on the other hand is also required for the impurity removal process. At present, feldspar grinding is mainly divided into dry method and wet method.

11.27 Feldspar Processing 11.27.1 General1 Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks. The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).
