Our range of flotation solutions include frother and collector programs for coal, copper, molybdenum, phosphate, potash, and more. All of our solutions address your process holistically, helping you optimize your flotation circuit to achieve greater selectivity, recovery, grade, and ultimately, cost performance.
Complex Phosphate Treatment Flowsheet using Mechanical Cells The following example describes a project in which an entire concentrator was converted from mechanical flotation cells to column flotation cells over a period of 2 years as part of a program to reduce plant operating costs. The ore is a volcanic phosphate ore containing approximately ...
Oct 15, 1997 Enhanced flotation reagents for beneficiation of phosphate ores. United States Patent 5962828.

Apr 23, 2020 Froth flotation is the most widely used phosphate ore separation process. Because of the nature of the phosphate ore, such as mineral types and content, disseminated particle size, its separation difficulty and flotation types varies. Phosphate ore is divided into siliceous phosphorite, calcareous phosphorite, and siliceous phosphorite according to the chemical composition of the …
Phosphate Beneficiation with Novel Collectors for Direct and Reverse Flotation: Beyond Low Cost Fatty Acids Pablo Dopico - Francolite ore with 19% P 2 O 5 3.5% MgO and 24.8% silica in flotation feed - Flotation targets: 32% P 2 O 5 - A scavenger circuit allows for recovery of additional phosphate quantities through
Phosphorus is common within geological materials. The average continental crust contains 0.27% P 2 O 5. 1 Phosphorus is the primary resources to produce fertilizer and phosphorous-based products. 2 Phosphorus is neither substitutable nor recyclable, therefore, the total demand must be provided through the mining, beneficiation and chemical processing of phosphate ores.
Dec 02, 2014 phosphate beneficiation, potential benefits of a single-collector flotation process have encouraged some investigators to search for a substitute for the Crago process. The advantages of a single-collector system over the double float process include reduced capital and energy costs, a simplified flowsheet, and the minimized discharge of

Flotation of phosphate Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate, a high grade of phosphorus is essential, as well as reduced levels of impurities such as magnesium, iron and aluminum oxides. Flotation is one of the key beneficiation methods.
