Depressants are an important factor affecting the flotation selectivity of minerals. However, there are very few studies on depressants for flotation separation of quartz and feldspar (Feng et al., 2018).Flotation depressants can generally be divided into two categories: organic and inorganic depressants (Wang et al., 2020).The effective …
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Weathered granite contains a high concentration of feldspar, quartz, and kaolin. However, while it becomes rich in clay due to strong physical weathering, the granite minerals that are not fully weathered are still very hard, which makes the grinding process more difficult and limits its use. This study proposes a multi-step process involving …
Since the major gangue minerals of spodumene are quartz and feldspar, flotation becomes the most important way to concentrate spodumene. In this paper, various researches related to spodumene flotation were reviewed. It can be seen that the surface properties of spodumene changed with the variation of size fraction, surface …
An improved method for producing high-purity quartz (Qtz) and potassium feldspar (Kfs) concentrates was developed using various chemical reagents. Froth flotation experiments on a Qtz–Kfs mixture showed that quartz could be selectively floated from Kfs in diluted hydrofluoric acid (HF) using a frother. Similarly, feldspar could be …
This data on chemicals, and mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses.. Flotation as a concentration process has been extensively used for a number of years. However, little is known of it …
A new collector prepared using decyloxy-propyl-amine (DPA) and α-bromododecanoic acid (α-BDDA) at a molar ratio of 1:1 increased the difference in the recovery of spodumene (82.14%) and feldspar (32.48%) significantly [53].The difference in recoveries of spodumene and feldspar was 27.47% while using DPA only, whereas the …
The micro-flotation results show that NaOL recovered 77% for spodumene and 37% for feldspar, while BAA recovered 87.87% for spodumene and 37.89% for feldspar. Afterward, they conducted tests using a mineral mixture to verify the favorable outcome of BAA, obtaining a recovery of 67.37% and a concentrate with 6.07% Li 2 O …
The purpose of this research is to recover slime waste from feldspar flotation plant at Attanee International Co. Ltd., Tak province. Slime waste with particle size less than 230 mesh, is found about 20% of the total ore feed. Since 1985, company has been producing slime waste approximately 200,000 tons, causing a huge pile of …
14 beneficiating plants and 1 grinding plant, 3 of which produce potash feldspar, the remainder of which produce soda, mixed feldspar, or feldspathic sand mixtures. ... From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture. A rotary dryer is then used to reduce the moisture content to 1 ...

The lithium pegmatite ore for batch flotation was also from the Jiajika Lithium Mine. The multi-elemental chemical analysis of the ore was conducted by acid dissolution and Atomic Absorption Spectroscopy (AAS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and the analysis results are shown in Table 2.As shown in …
Flotation Flotation is widely used in the production of spodumene concentrate from hard rock lithium deposits [6,7,8].Flotation is employed to recover spodumene from the original feed or from the combined DMS middlings and undersize fraction to produce concentrate suitable for downstream operations such as …
Much of the published information on feldspar flotation relates to fundamental studies seeking to elucidate the mechanism of the separation and recovery of feldspar with anionic or cationic collectors and activators. However, the separation schemes currently being used industrially are largely the same as those first proposed …
