Flotation

COARSE FLOTATION

COARSE FLOTATION OFFERS IMPORTANT SAVINGS THROUGH REDUCED OPERATING COSTS

Grinding cost varies greatly depending upon the size reduction required. For example, it takes approximately 50% less horsepower to grind from ½” to 48 mesh than it does to grind the same material from ½” to 100 mesh.

Many minerals are liberated at a coarse mesh

COAL FLOTATION

The flowsheet in this study illustrates the general practice in the United Kingdom. A large number of coal preparation plants have been established by the National Coal Board during the past 10 years. The primary consideration is to achieve a maximum recovery of low ash coal. The secondary consideration is to reclaim the plant water and avoid pollution

Flotation Material Balancing Excel Solver: Mass Balance Calculations Example

example-material-balance-calculations-using-excel-spreadsheetFor a flotation circuit, material balance calculations define an engineering problem where flow parameters between unit operations are partly known. The purpose of a material balancing is to mathematically examine the known flow parameters to solve for the unknown flow parameters. Two main types of material balances are commonly made:

  • design material balance
  • operating plant material balance.

The design
