Magnesite is a carbonate mineral. Xinhai mainly applied direct flotation process and Reverse Flotation Process for beneficiation of magnesite. 【Application】 Reverse flotation process is applied for high grade ore with less calcium & iron (Fe). As for low grade ore, Xinhai combines the two methods.
Low grade magnesite coexisting with dolomite was purified by flotation. A process of reverse flotation to remove silicate minerals- positive flotation to concentrate magnesite was explored after the systematic process mineralogical investigation. Influence of different conditions such as grinding fineness experiment, collector experiment and combined modifiers experiment was also investigated.
Results have shown that a high-grade magnesite was obtained after subjecting the non-magnetic portion of the processed sample twice at 1.8 T. It was possible to increase the magnesite content up to 91.03 % while reducing the iron content to 0.32 % by using magnetic separation.
How to Recycle Magnesite Chrome in Copper Smelting Furnaces. ... The existing deposits in the United States are low grade and would only be used if outside sources became unavailable. Approximately 97 pct of the chromite consumed in the United States is imported from the Eastern Hemisphere; the main suppliers are the Soviet Union, Republic of ...
The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization. In this study, process mineralogy and beneficiation of the ore were carried out in the laboratory.
Beneficiation testwork completed by CRAE determined that lower grade (+35% MgO) can be easily beneficiated by flotation to remove the dolomite (and most of the SiO2) leaving high grade magnesite with low iron. CRAE concluded in September 1984 that no further exploration work was required at this
A process for the recovery of nickel and cobalt from laterite ores, the process including the steps of: a) beneficiating the ore to separate it into a beneficiated upgraded ore fraction and a coarse, siliceous low grade rejects fraction which is substantially free from fines and clay materials; b) separately processing the upgraded ore fraction for the recovery of nickel and cobalt; and c ...

Flotation studies on low grade magnesite deposits from Sujikonda near Daroji Bellary district, Karnataka state P. Gopaia Reddy * R. Nijagunappa, * G. S. Kumar * S. J. Gopala Krishna, * M. R. Patil and * B. Somasekar INTRODUCTION Magnesite, an important basic refractory raw material, has been in short supply in recent years.
One way is to crush the limestone to −3 mm size and then to process it in a scrubber and classifier. Another entails grinding the raw feed to less than 200 mesh and then to carry out beneficiation by a froth flotation method,,, . In the present case, a low grade limestone sample was processed using the column flotation technique.
exploitation. The problem of the utilization of low grade magnesite ore is becoming more and more serious, although it is difficult to beneficiate magnesium ores because the associate minerals are also other magnesium containing ores with similar characteristics and reciprocal influences in the beneficiation process[3,4]. It is very important that
Low grade magnesite ore flotation process: the impurity in raw ore cannot be removed if only apply the methods of reverse flotation process. So for the low grade magnetsite, we usually combine the two methods, reverse flotation process (one roughing – one cleaning) & direct flotation process (one roughing – one scavenging).

In this study low-grade magnesite (Halaib deposit), from the Southern Eastern Desert, was used. Its chemical composition is given in Table 1. It is clear that magnesite contains 37.2% of MgO while the theoretical MgO content in pure magnesite is 47.82%. This indicates that the studied magnesite samples are of low-grade ore.
