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 Hydrofluoric acid (HF), which is the main regulator used in the flotation of feldspar, may cause serious environmental and health-related problems. Therefore, to Systematic review of feldspar beneficiation and its

Scalable recycling of feldspar slime into high-quality concentrates
The recovery of feldspar concentrates from slime has therefore become an important issue in the sustainable utilization of feldspar resources [17]. Feldspar slime is extremely fine in particle size and its impurity minerals are significantly entrained in the flotation process, resulting in poor flotation efficiency and selectivity.While there is a significant amount of spodumene flotation research available, the evidence indicates that there have been no major changes to the fatty acid flotation process since the 1940s.

Flotation separation of spodumene and albite with activation
However, the gangue minerals, such as feldspar and quartz, usually coexist in spodumene ore,which increases the difficulty of spodumene enrichment in flotation. Particularly, feldspar has similar chemical composition, crystal structure, and reagent action sites to spodumene [9,10,11], which is the main factor limiting the quality of spodumeneTo bring out the importance of roasting before the dissolution process, different parameters such as roasting temperature, duration, and feldspar—CaCl2 ratios were tested.

A froth flotation process is used for most feldspar ore beneficiation. Figure 2-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acidThe most common beneficiation method for feldspar is flotation with a cationic (amine) collector under acidic conditions.

Understanding the flotation separation of Na and K feldspars in
Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Na-feldspar (albite) and K-feldspar (microcline) minerals were investigated in the presence of K + ion as counter ion. In order to identify the role of K + ions on the selective separation Silica Content of Potassium Feldspar Ore by Flotation reduce the iron content [7, 13, 14]. Extensive research has been published on the application of various collectors in feldspar flotation. Cationic collectors of amine and hydrofluoric acid have been commonly used as feldspar activators to reduce the silica content in feldspar ores [4, 5, 7,The Laboratory Investigations of Reducing Iron and Silica Content

Two-stage reverse flotation process for removal of carbonates
Flotation in this case is carried in two stage operation. Anionic–cationic double reverse flotation was found to be an appropriate method to upgrade grade phosphate rocks. The two steps process is to float the carbonates at pH = 4.8–5.2; the second stage includes flotation of the quartz at pH = 7.8–8.5.
