Sodium oleate (NaOl) is widely used as collector for oxidised ore flotation, and residual NaOl in mineral processing wastewater is a serious threat to mine environment. In this work, the feasibility of electrocoagulation (EC) as an alternative for chemical oxygen demand (COD) removal from NaOl-containing wastewater was …
The non-polar group creates the hydrophobic surface in contact with the water. The mechanism of mineral–collector bonding depends on the collector type and mineral surface nature and charge, and can result in the collector being physisorbed or chemisorbed (Bradshaw, 1997). Sulphide minerals are semi-conductors, i.e. they can …
The valuable product from a mineral processing plant. Concentrator: A plant where mineral processing takes place – also called a mill. Conditioner: A tank, usually agitated by an impeller, used to allow mineral particles to react with reagents. Controlled Variable: Variable that the controller tries to maintain at set point: Coriolis Meter
Flotation consumes a large amount of water, which about 4 ~ 7 tons of water is required for one ton of raw ore processing and generate mass of mineral processing wastewater (MPW) [1], [2]. From the perspective of saving water resources and production costs, the wastewater collected from mineral processing is usually recycled by enterprise.
Although most of the xanthates added to the flotation circuits are adsorbed by target minerals, about 50 % of the xanthates remain in the discharged tailings pulp, with concentrations ranging from 5.0 to 40.0 mg/L (Rezaei et al., 2018, Tan et al., 2021, Zhou et al., 2021b).Xanthates can escape into the environment from mineral processing, for …

The flotation performance of the collectors was evaluated using a laboratory mechanical flotation cell at different process parameters such as pH, collector dosage, diesel dosage and flotation time. The two collectors evaluated were a …
In cases where clay minerals are present in the ore, we can provide collectors for the slime flotation step needed prior to potash flotation. We also offer collectors for reverse flotation where halite is floated to beneficiate carnallite. Rely on our 80-years of expertise as the world-leading supplier of collectors to the potash

A Broad Portfolio for Mineral Processing. Syensqo offers a leading portfolio of flotation reagents for improved metallurgical outcomes. Our portfolio consists of collectors for mineral flotation, frothers, depressants, and dispersants.
Collectors, some of the most important reagents used in the froth flotation process, are used to modify the surface properties of minerals to control how they float. They selectively bind to the surface of target minerals and impart hydrophobicity to those mineral particles, a necessary condition for air bubble attachment.
Mineral processing is a form of extractive metallurgy that separates valuable minerals from the ore into a concentrated, marketable product. Mineral processing is also known as mineral dressing. ... Froth flotation uses a chemical collector and frother that forms bubbles on the surface of the slurry that hydrophobic materials bind to. The ...
