Minerals processing

Clay is a common mineral contaminant and water recovery from discarded effluent is problematic as a result of its particle size being 10 pm due to hydrolytically weakened delami-nation. At a presence of himdreds to thousands of tonnes per day at each site, solid-liquid separation becomes a significant cost to the viability of operation. [Pg.154]

The value streams in mineral processing also generate similar separation demands through the operations to separate and concentrate the products in the form of particulates or solutions. [Pg.154]

Typically the flocculants used are anionic or non-ionic in nature and, as a result, attachment to particles is via salt linkages or hydrogen bonding. [Pg.154]

Choice of optimum polymer tends to be carried out by empirical testing [29] due to the [Pg.155]

Below are examples of typical mineral processing operations that illustrate the position of [Pg.155]

Flotation. Flotation is a gravity separation process which exploits differences in the surface properties of particles. Gas bubbles are generated in a liquid and become attached to solid particles or immiscible liquid droplets, causing the particles or droplets to rise to the surface. This is used to separate mixtures of solid-solid particles and liquid-liquid mixtures of finely divided immiscible droplets. It is an important technique in mineral processing, where it is used to separate different types of ore. [Pg.70]
