Efficient recycling of waste printed circuit boards by flotation has become a research focus. In this study, waste printed circuit boards were treated by alkaline immersion to enhance the flotation efficiency. Firstly, the SEM-EDS analysis of the crushed products shown that metal and nonmetal were completely liberated in the -0.25 mm fraction.

The coarse particle flotation and regrind circuit has a profound impact on our MissionZero ambitions. It enables upstream and downstream unit operations to perform in more efficient ways to further the goals of MissionZero beyond the flotation circuit itself. This means optimised grinding is possible.

form of water-based slurry) is transported to the flotation circuit where the copper sulfide ore minerals are concentrated and separated from the nonmineralized material by a series of rougher (see fig. 3) and cleaner flotation cells, which produce successively higher grade concentrates. This flotation slurry, also
flotation recovery is an exponential function of flotation time. The differential equation of Zuniga (1935) can be written as: dC KC dt (1) where C(t) is the concentration of floating particles remaining in the flotation chamber up to the flotation time t, K is the flotation rate constant.
Cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit. Many ores contain multiple valuable minerals that can be floated into separate concentrates. Examples would include a lead-zinc ore, in which the lead and zinc minerals are recovered sequentially into separate concentrates.
