A method of beneficiating a phosphate ore comprising apatite and including dolomite impurities, said method consisting essentially of the steps of: (a) reagentizing a sample of said ore having a particle size in the range of from about 75 microns to 420 microns, with an aqueous solution having a pH of from about 4.0 to about 7.0 and containing ...

Method of beneficiating phosphate ores International

The method of claim 1 wherein the alkaline earth metal carbonate mineral impurity is dolomite; the deslimed ore fraction is split at about 16 mesh in step (b); the middle ore fraction is split at about 28 mesh in step (d); and the flotation feed produced in step (f) is comminuted, sized and deslimed to a deslimed particle size of less than ...

Role of ore mineralogy in selecting beneficiation route

The role of ore mineralogy in selecting the most adequate concentration method for magnesite-dolomite separation was found to be detrimental. The microscopic analysis showed that dolomite is stained with goethite and lepidocrocite (weakly magnetic minerals), while magnesite is stained with hematite and magnetite (highly magnetic mineral).

Minerals Free Full Text A Review of Flotation

It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg carbonates have high levels of adverse effects on separation efficiency.

Flotation of a carbonate rich sedimentary phosphate rock

A large portion of the world's phosphate reserves are sedimentary type containing appreciable amounts of carbonate minerals. These are the most difficult type of deposits to beneficiate. The depletion of other reserves easier to beneficiate, necessitates research to find methods of mineral processing for carbonate rich sedimentary phosphate deposits. In this study, a new flotation method is ...

A Review on the Beneficiation Methods of Borate Minerals

The modern boron applications have adsorbed the mineral processors’ attention to improve typical boron mineral’s (BM) beneficiation methods. In this regard, dry treatment and pretreatment processes—such as magnetic separation and calcination as environmentally friendly methods, due to their minimal or zero adverse effect on the environment—need more consideration.

Classification and beneficiation method of manganese ore

Beneficiation method of manganese bearing iron ore The content of manganese in this kind of ore is low, only 5% – 10%. At the same time, it has the characteristics of fine disseminated particle size and close symbiosis of iron and manganese minerals, so it is difficult to recover by mechanical beneficiation.

Five flotation methods help you processing lead zinc

Aug 23, 2021 The above are the five major flotation methods of lead-zinc oxide ore. These methods have their own advantages in use. When selecting the flotation method, beneficiation tests should be carried out first. According to the ore grade, mineral composition, and mineral …

Mining and Beneficiation of Phosphate Ore IntechOpen

Apr 13, 2016 The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of important parts of …

Beneficiation of a High Dolomite Phosphate Ore . . Optimiz

Figure 1. The flowsheet described in the figure was designed to achieve beneficiation by removing the majority of the fine dolomite during the first stage, quartz and some portion of coarse dolomite during the second and the remaining coarse dolomite during the third stage. Feed 500 a Condit/ooing (pH = 5.5) Reagent (In sequence) TIme. min.

Continuous Beneficiation of Dolomitic Phosphate Ores

trate from the double-float method with a carbonate collector, a phosphate depres sant, and a pH regulator. The dolomite was removed as the overflow product, and the phosphate concentrate was the under flow (~). Laboratory beneficiation studies have been completed and reported for two south 3 Florida high-MgO ores (9).
