The bench flotation tests were conducted in a Wemco machine equipped with a 3.9 L cell, using 1.5 kg iron ore aliquots in 50 % solids (w/w) pulps. The pulp was conditioned at 1250 rpm, initially with starch for 5 min and then with the collector and frother solutions for 1 extra minute, when it was diluted to 42 % solids for flotation.

Metallurgical-grade silicon-refined waste slag (MGSRS) was produced during the MG-Si refining production process, which occupies huge amounts of land resources, caused the loss of nearly 110,000 tons of MG-Si every year. Therefore, it is of great significance to recover the elemental silicon from MGSRS. However, because …

Before the magnetic separation experiment, the key parameters of the steel-wool matrix (e.g., layers, type specification, and spacing) were experimentally optimized using the slice matrix analysis method (Chen et al., 2021).The characteristic parameters, such as solid concentration and flow velocity of the high-silicon iron ore tailing pulp, …
Reverse flotation is a process that the gangue minerals report to froth products while the valuable minerals stay in the flotation cell as tailing. According to the types of the collector, it can be generally divided into anionic collector reverse flotation and cationic collector reverse flotation.
Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica. In direct flotation, oleic acid or its sodium salt is the preferred reagent. Several studies on oleate-hematite interactions suggest that the oleate adsorption on hematite mainly depends on solution pH (Paterson and Salman ...
