EFFECfS OF DISSOLVED MINERAL SPECIES ON THE ELECfRO ...

The interfacial behavior of salt-type minerals such as calcite and apatite is governed to a large extent by their electrochemical properties which in turn are governed by pH and concentration of dissolved mineral species. In mixed mineral systems, the interfacial behavior of various minerals is often quite different from what might be expected on

THE DEVELOPMENT OF A MINERAL BENEFICIATION PROCESS .

Abstract. An account is given of the investigation which led to the establishment of a commercial process for the beneficiation of monazite together with a differential recovery of a copper-bearing concentrate from the unique lode occurrence at Steenkamp's Kraal in the Northern Cape Province.

Flotation in Seawater | SpringerLink

A classification of flotation processes carried out in concentrated electrolyte solutions, e.g., seawater, is proposed using the most obvious features of these processes: low or high content of Mg2+ and Ca2+ ions, pulp ionic strength, and pH. The first distinguishable group is the processes carried out in NaCl/KCl solutions, about 0.5 M in the case of salt flotation of inherently hydrophobic ...

Primary mineral - Wikipedia

A primary mineral is any mineral formed during the original crystallization of the host igneous primary rock and includes the essential mineral(s) used to classify the rock along with any accessory minerals. In ore deposit geology, hypogene processes occur deep below the earth's surface, and tend to form deposits of primary minerals, as opposed to supergene processes that occur at or near the ...

Boron Minerals Flotation

Beneficiation of these minerals, apart from the boron-rich salt lakes, requires a preconcentration step to remove the unwanted clay minerals usually in some form of scrubbing operation. This normally follows decantation or selective flocculation to separate the clay and recover the boron minerals.
