Four independent geo-metallurgical test work programs (mineral characterization, comminution, froth flotation and cyanide leaching) were carried out on the different metallurgical composites.
"In the metals and minerals industry, froth flotation is the most important way of recovering valuable raw materials from ores," explained Dr.
Being medium-grade in their current form, different beneficiation techniques including gravity separation, magnetic separation and froth flotation were employed to assess the up-gradation potentials of the Dammal Nisar ore.
This new method, described in a paper in the journal Sustainable Materials and Technologies, uses an old mining technique called froth flotation.
[11] used the froth flotation technique to upgrade Turkish low-quality oil shale by employing amine-type collectors.
In recent years, froth flotation has been investigated extensively with major focus on studying the effects of various operation and design parameters on product yield and recovery (Cheng et al., 2016; Liao et al., 2016; Patil et al., 2010; Mondal and Mohanty, 2009; Jena et al., 2008; Dell, 1964).
Ore will be processed through a standard crushing and grinding circuit followed by froth flotation. The operation will produce two concentrates: a lead concentrate that will assay approximately 69% lead and 1,100 g/st silver, and a zinc concentrate that will assay approximately 56% zinc and 350 g/st silver, with an approximate gross revenue split of 42% zinc, 43% lead and 15% silver.
The HydroFloat Separator is both a flotation device and a density separator, combining the advantages of froth flotation and gravity separation.
Froth flotation has found extensive use in the mineral processing industry especially in treating low grade ores.
It details the theories of origin and formation of coal, its constituents, sampling, calorific value, rank, properties, classification, coking tests, and size, proximate, and ultimate analysis; processing aspects, namely unit operations, screening, size reduction, dewatering, beneficiation processes, gravity concentration processes, heavy medium separation, jigging, flowing film concentration, froth flotation, centrifugal separators, and coal washing; and coal utilization, including carbonization, combustion, gasification, liquefaction, and capture and storage.
