WORLD LeADeR IN ADvANceD FLOTATION TecHNOLOGY

2014-7-17  Unlike conventional flotation cells, columns do not use mechanical agitation. Feed slurry enters the column in the upper third of the body and descends against a rising swarm of fine bubbles generated by a gas sparging system. Targeted particles collide with and attach to the bubbles and rise to the top of the column.

Froth Flotation of Iron Ores - article.sapub

2012-1-2  4.2. Column Flotation The application of column cells in the mineral processing industry has gone from virtually zero in 1983 to wide acceptance in 1990[55-57]. The major operating difference between column flotation cells and mechanical flotation cells is the lack of agitation in column flotation which reduces energy and maintenance costs[58].

Chiral columns of 1 × 1 × 4, 2 × 2 × 8, and 3 × 3 × 12 were tested in compression to identical strain values (ϵ axial = 0.05), and twist was measured by tracking a single point at the center of the lattice. Experimental results are shown in fig. S10D. The 1 × 1 × 4 column shows larger values for twist than does the 2 × 2 × 8 column.
