BENEFICIATION OF DOLOMITE AND MAGNESITE
Purification of sphalerite concentrate in the chemical and flotation way. In this paper the results of the investigation of magnesium removal from zinc concentrate derived from zinc-lead ore enrichment plant have been presented. The characteristics of the initial concentrate and the occurrence forms of dolomite in this material are estimated.

Dolomite mining process is the solution of separating dolomite concentrate from Dolomite raw ore. Based on mosaic structure of the Dolomite mine and years of mining process experiences we applying Dolomite mining process of two-stage crushing washing then three-stage separating flotation process will be used to process Dolomite with complex

Closed-circuit reverse flotation tests using GOFA as the collector resulted in an excellent concentrate with 28.46 wt P 2 O 5 and 0.65 wt MgO corresponding to a P 2 O 5 recovery of 87.2 . GOFA was demonstrated to exhibit outstanding selectivity for dolomite in the reverse flotation of collophanite ore.

Micro-flotation results indicated that the addition of P(AA-AMPS) could achieve the efficient separation of apatite from dolomite at pH 8.5 by selectively depressing the dolomite flotation in which more than 87.4 of apatite was recovered whereas the dolomite recovery was less than 14.7 .

The XRD analysis of the flotation concentrate indicates that the content of abundant carbonate minerals of dolomite significantly reduces the A/S ratio in the concentrate. As these minerals react with hydrochloric acid (Reddy et al. 1999) the hydrochloric acid leaching of the concentrate was carried out to improve its Al 2 O 3

The flotation process lasted 3 min for each test. Following this the flotation recoveries were calculated based on the weights of concentrates and tailings. For artificial mixed minerals flotation experiments the mass ratio of apatite and dolomite mineral was 1 1 for binary mixture. The flotation process was the same as single mineral tests

flotation process. Perhaps the most promising process for Florida dolomitic phosphate pebbles is the CLDRI process developed under FIPR funding. In that process dolomitic pebbles are ground to suitable particle sizes (normally to 100 mesh) for liberating - dolomite. The ground slurry is subject to dolomite flotation followed by either silica or
Chat OnlineThe flotation of apatite and dolomite in orthophosphate
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. Further the selective depression mechanism of NaPP was studied through zeta potential measurements
