MINING AND PROCESSING

Imerys Refractory Minerals' milling technology is a complex process where the methods depend both on ore type and on the final application. To obtain exactly the right particle size and top cut for a given application, we use a variety of techniques including compressed air, steam and impact milling – many of which have been developed in-house.

Magnesium

Magnesite is favoured as the source of magnesium because chlorine is recycled within the process rather than being disposed of as a waste or a by-product. The silicothermic process mixes calcined dolomite or magnesite with ferrosilicon (a combination of iron and silicon metal) to produce a magnesium vapour which is then condensed in cooling vessels to form magnesium

Minerals

Magnesite ores are important resources in the production of value-added magnesium materials. Generally, low selectivity of conventional collectors and the requirement of a large amount of depressant has been a motivation for researchers to identify alternate collectors. In this work, the role of potassium cetyl phosphate (PCP) as a new collector in magnesite flotation is

A New Approach for Reverse Flotation of Magnesite

Magnesite and dolomite are two salt-type minerals. The surface characteristics of these two minerals are almost the same. It is very difficult to remove dolomite from magnesite ores by flotation process. The present study was performed to develop a new collector and a better flotation scheme for magnesite from dolomite. The flotation tests show that

True Flotation and Entrainment of Kaolinitic Ore in Batch

18/6/2014The effect of particle size in the flotation process was analyzed by particle size distributions of four fractions (25 m; +25–45 m, +45–63 m; and 63 m). The contribution of entrainment is similar for the three oxides and the degree of entrainment decreases with increasing particle size; however, the recovery by true flotation is different because of its

Flotation in the 2010s: Focus on mineral processing

1/1/2019The two minerals mainly investigated in the present, magnesite and dolomite, although of the same type (i.e., salt-type minerals) did not behave similarly as far as flotation is concerned. Dolomite, being here mineralogically crystalline, was more amenable to processing, giving high flotation recoveries at the size range used.

Processes

Flotation constitutes a gravity separation process, which originated from the minerals processing field. However, it has, nowadays, found several other applications, as for example in the wastewater treatment field. Concerning the necessary bubble generation method, typically dispersed-air or dissolved-air flotation was mainly used. Various types of biological materials
