Dewatering Screens – MEKA
What is a dewatering screen? Any material that comes into contact with water will get wet. Material needs to be washed or transported as concentrate and waste pulp in the enrichment of the ore for the production of the aggregate and sand necessary for ready-mixed concrete production in ore preparation facilities and in the construction sector.

Optimal ceramic filtration operating conditions for an iron-ore concentrate
Highlights. Ceramic filtration was found to be suitable for final dewatering of iron ore concentrate. Optimum filtration was found with the use of flocculent and at pH of 7. Nitric and hydrochloric acid are recommended for filter cleaning. The unit can consistently filter 2240 kg/m 2 hr of slurry and produce a cake containing 8% moisture.

Patra et al. (2016) have studied and improved dewatering of iron ore fines by the usage of surfactants. In their primary studies, they found that the main problem with the dewatering process was adherence of the ultra-fine particles to the iron particles. Surfactants improved dewatering by increasing the hydrophobicity.

Concentrate Dewatering & Thickening
The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...
