  • Evaluation of control performance methods, monitoring

    A flotation plant consists of a number of flotation cells in series. Each flotation cell has a mechanism for air injection; launders for collecting the froth located at the top of the cell, and structures to funnel the froth towards the launders. Pulp level control in the flotation cells is a complex task because the operating limits are tight and the operating conditions vary (J228;ms228; Jounela et al., 2002).

  • How to Calculate Buoy Floatation in the Water Sciencing

    Flotation was first explained by the classical Greek mathematician, Archimedes, who formulated the famous principle that bears his name. Archimedes' Principle states that an object completely or partially immersed in a fluid (a liquid or gas) is acted upon by an upward, or buoyant, force equal to the weight of the displaced fluid.
