La ecuación de Pierre Gy es la más utilizada en el muestreo de minerales. Esta ecuación está basada en cuatro parámetros: factor de forma, factor de granulometría, factor de mineralogía y factor de liberación. La práctica usual es considerar

Gas dispersion is one of the key factors in the mineral flotation process. It can be expressed by many variables such as bubble size, gas holdup, gas superficial velocity and bubble surface area flux ( S b ). In particular, S b has been found to have

Pierre Gy's equation is widely used in ore sampling. This equation is based in four parameters: shape factor, size distribution factor, mineralogical factor and liberation factor. The usual practice is to consider fixed values for the shape and size

There are many applications in the mining industry where various material features may only be calculated by means of an image analysis method. Good examples of this are size analysis of open-pit muckpiles, on-line size analysis of ore on a belt conv

Solid concentrations, calculated from slurry density measurements, particularly in hydrocyclones streams, are important to both grinding circuit control and flotation control. Due to the multiplicity of grinding lines, slurry density sensors in each
