dolomite flotation tailing

Improving flotation separation of apatite from dolomite

9/1/2020· The results from flotation experiments illustrated that PAMS effectively depressed the dolomite flotation whereas it exhibited weak influences on the floatability of apatite. It was also found that the reagent scheme of 14 mg/L PAMS and 100 mg/L NaOl could effectively remove dolomite from apatite at pH 9.00.

BENEFICIATION OF DOLOMITE AND MAGNESITE

with 1.75% insol. Cationic flotation tests using amine 220, at PH 9.7, the dolomite concentrate (flotation tailing) analysed 2.7% insolubles. MAGNESITE This is important raw material for the manufacture of refractory bricks for use in the metallurgical industry. Large deposits of magnesite are located in the Salem district of Tamil Nadu.

Selective adsorption of a high-performance depressant

10/15/2020· The micro-flotation of dolomite and magnesite was carried out in a laboratory flotation device (mechanical agitation) with a 30-mL detachable cell and a stirring speed of 1992 rpm. The flotation slurry was prepared by adding a single mineral (2 g) or artificially mixed minerals (1.2 g magnesite and 0.8 g dolomite) into 25-mL DI water in the flotation cell.

Effect of Sodium Pyrophosphate on the Reverse

Abstract. In this study, the effect of sodium pyrophosphate (NaPP) on the separation of apatite from dolomite by flotation was systematically investigated. Flotation results revealed that NaPP could selectively depress the flotation of apatite, thus realizing the separation of apatite from dolomite.

Gravity Separation of Zinc Mine Tailing Using Wilfley

1/16/2020· The flotation process is used to concentrate the zinc ore known as willemite. The process generates a residue consisted of hematite and dolomite. The residue used in this work presents desegregated hematite and dolomite particles, previously identified by MEV. In such a way, this work aims through gravity separation to concentrate the mineral phase

By contrast, the dolomite grade decreases from 50.15% to 13.22% with an increase in the dosage of SH and the flotation recovery of dolomite decreases from 97.46% to 7.95%. It indicates that, with the change in the adding sequence of SH and Na 2 CO 3,the grades of magnesite and dolomite have different change trends and the recovery of magnesite has declined.
