Froth Crowder - 911 Metallurgist

14/09/2015  The concept of froth crowders and was developed in the early 1950s. The need for crowding froth out of a flotation cell grew along with the size of flotation machines and their cells. The 1st froth crowder device was patented in 1956 (Fig 1 and Fig 2). What I call the crowder

Column Flotation • Theory and Practice

Separation of valuable minerals from gangue is far from ideal in conventional mechanical cells. Column flotation, invented in the early sixties, proved to be a better alternative to the conventional cells. The main advantages of column flotation are : i) improved recovery, ii) higher grade, iii) lower capital and operating costs, iv) less wear and tear due to absence of moving parts and v) requirement of less floor

01/05/2006  The froth stability column was used for measuring froth stability in the second cell of the bank. Measurements were carried out using a cylindrical (0.3 m diameter), vertical (1.5 m) column.The column was secured onto the main railing on top of the cell and inserted into the outer froth crowder, and to a depth of approximately 0.25 m below the pulp–froth interface ().

Column Flotation - SGS

The froth of a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a “rain” of water onto the surface of the froth. The key objective of water 2washing the froth is to minimize recovery of ...
