• Extending the upper particle size limit for coal flotation

    Pilot-scale flotation tests were conducted using a bank of four Denver Sub-5 flotation cells (28 litres per cell). In these tests, the 3 mm x 0 coals sample was fed to a 14-mesh (1.41 mm) vibrating screen. The screen underflow was sent to a sump where novel flotation reagents (01DU113 or 01DU133) were added in the amount of 800 g/t and agitated.

    Some results for floatation and flotation with various related_terms are below. M = millions of hits. k = 1000's of hits. e.g. "Australia 420 k / 10.9 M" = 420,000 hits for floatation and Australia, 2.29 million hits for Australia and flotation. Very obviously this method has methodological deficiencies, but it is also demonstrably useful.
