However, in froth flotation plants, water quality is particularly likely to influence the process performance (Johnson, 2003), making water management both an environmental and production-related issue (Levay and Schumann, 2006). The challenge is thus to develop a systemic approach where water quality and its influence on the …

Froth flotation represents the most versatile separation method in mineral processing. It takes advantage of the different surface minerals properties to selectively separate more hydrophobic minerals from less ones towards interactions with air bubbles. Flotation has been initially developed to treat the sulfide minerals of copper, lead, and zinc.

The scale-up relationship was developed based on dimensionless parameters. First, a scale-up factor (ξ) was defined as the ratio between the actual flotation rate (k AC) of the collection zone in a perfectly mixed industrial cell (N = 1) and the flotation rate (k B) in a laboratory batch cell, (1) ξ = k AC k B The apparent flotation rate constant for the …

The model for the froth recovery of water is expressed as an exponential function of the mean froth residence time. Two forms of froth recovery models are adopted by Harris (2000): (16) R fw = ( 1 - α w) · exp ( - β w · τ f) + α w (17) R fw = Ω · exp ( σ · V f - χ · τ f) where αw, βw, Ω, σ and χ are constant. Eq.

Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.
