1. Introduction. The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).Separation of mineral particles by …
Froth images contain much information on flotation behavior; an experienced operator can adjust the concentrate quality by observing the froth status in coal flotation. This indicates the feasibility of determining the coal flotation concentrate quality using froth images [[8], [9], [10]]. Many researchers have proposed various machine learning ...
After each flotation experiment, the concentrate and the tailing were filtered, dried, and weighed. Flotation recovery (R) was calculated using Eq.2. (2) R = m 1 m 1 + m 2 × 100 % where m 1 and m 2 are the mass of the floated and un-floated fractions, respectively. Each flotation experiment was repeated three times and the reported …
Each flotation bank is comprised of dozens of flotation cells. This is done to ensure both high concentrate grade in the final product and high overall recovery.

Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium resources. Here, the separation of ilmenite from VTM ore is studied by combining magnetic separation and flotation technologies. In …
