The results indicate that DDA/HQ330 mitigates the negative effect of feldspar slime on the flotation of lepidolite. The schematic diagram of the action of the two collector systems in the flotation process is shown in Fig. 13. The results of the micro flotation test indicate that the recovery of lepidolite was not significantly affected by ...

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 selectively floated from …

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 grinding, desliming, and …

2. Flotation process. The flotation process can effectively remove iron from clay and fine-grained iron-containing minerals, but the effect is not good for hard ores. For severely weathered ores, secondary sludge may …
Details
Quartz and feldspar are usually exist in symbiosis in nature, and they are difficult to be separated effectively by conventional physical methods owing to their similarities in crystal structures and surface characteristics. Flotation is the most resultful method, and especially, flotation with hydrofluoric acid (HF) is the most efficient way. Because HF may cause serious …

It was found that the sphalerite showed a certain degree of natural floatability ground by the porcelain ball mill, while the sphalerite lost its natural floatability ground by the steel ball mill. Smithsonite can be directly recovered by the flotation process with advanced xanthate or collector of fatty acid, but the selectivity is very poor.
