On a flotation column cell, the variation of concentrate flowrate, clean coal yield and product grade with air flow rate are shown in Figure 4.
Horizontal cyclones can reduce the quantity of fines in the cyclone underflow as described by Hochshied (1984). A number of plants are now operating horizontal
The oxidation kinetics of pyrite and refractory gold concentrates in acidified ferrous sulfate solutions in the presence of oxygen-sulfur dioxide gas mixtures has been studied.
A comprehensive analysis of the entire range of related studies would require a lengthy discussion. Instead, this paper will focus only on the work of
The most common zirconium bearing minerals are zircon, the zirconium silicate ZrSiO4, typically produced from heavy mineral sands in Australia and India, and baddeleyite, the
The claims which supply oxide and refractory ore feed to the Cortez milling facility are located in both Lander and Eureka Counties. These include the
The results of column leaching tests on 3 different mixed oxide/sulfide ores from a Chilean deposit are presented. The 3 samples contained different ratios of
Pure rhenium is a refractory metal with a very high melting point of 3180°C. Extraction of rhenium from molybdenite concentrates and other primary sources has
Two different circumstances must be addressed for the reduction or elimination of overload risk: a) in existing operations, or b) in the design of new
Critical size material is defined as ore that is too small to be effective grinding media and too large to be ground. This data showed
