Therefore, the flotation recovery and separation efficiency of antimony from mine wastewater can be improved effectively through exploring the adsorption mechanism and finding a suitable collector. Xanthate is the most widely used collector for sulfide flotation because of its easy synthesis and low price.
The oxides are recoverable by gravimetric methods, typically jigs and tables. The sulfide ores are recoverable by flotation. During World War II, the United States relied on Mexico for antimony for military applications. Historically, Mexico was at one point the second largest producer of antimony in the world.

The enrichment of antimony ore to increase its quality is achieved through various methods, including positive flotation, reverse flotation, bulk flotation, and …
As illustrated in Fig. 4, at increasing pH of the solution from 3 to 5, the efficiency of HA removal by the AEC-PS process was improved from 87.4 ± 4.5% to 94.3 ± 4.7%, which may be due to the ...
A reagent dosage hybrid control strategy for the antimony flotation process is proposed in this work. This strategy consists of two parts: reagent dosage tracking control based on a froth size probability density function (PDF) and reagent dosage compensation control based on a distributed-machine vision predictive model. The proposed method …
mony oxide flotation is fully discussed via modern molecular orbit theory. Key words antimony; flotation; activator Recovery of fine antimony oxide with froth flotation is one of the most difficult problems. The oxide mineral is not only to be slimed easi- ly, but also tends to form colloid in water solu-
The new high antimony material will be mined as a result of the planned 4th cut back. Polyus plans to start selling Au-Sb flotation concentrate on the global market and is already produced it successfully (Au 50-100 g/t; Sb 20-40%), with future plans to also produce antimony metal.
USAC has produced various antimony products since 1969 and is a fully integrated mining, transportation, milling, smelting, and selling company. USAC operates the only significant antimony smelter …
Antimony is also alloyed with tin to make pewter items such as plates, pitchers and cups, used mostly for decoration. One use of antimony, which is declining, is to make type metal for newspapers and magazines. Antimony is one of very few substances (bismuth and water are two others) which expand when it cools and freezes.
The Costerfield operation is located in Victoria, Australia, within the Costerfield mining district, approximately 10 km northeast of the town of Heathcote, Victoria. ... ball mills, rougher, scavenger, cleaner flotation, gravity circuit, and filtering. Gravity gold concentrate is sold to a refinery in Melbourne, Victoria, and gold-antimony ...
This paper focuses on the environmental leaching of antimony, a critical mineral, using deep eutectic solvents. Mining residues often contain embedded antimony, posing environmental risks. Deep eutectic solvents, known for being low in toxicity, cost-effective, and environmentally friendly, present a promising avenue for sustainable …

The flotation agent helps to form a stable froth of air bubbles, which attach to the mineral particles and cause them to rise to the surface, where they can be collected. The flotation agent works by selectively binding to the surface of the mineral particles, making them hydrophobic (water-repelling).
