The vacuum ranges from 67 68 kpa The wash water is running full across the filter length There are no cracks on the filter cake No No Not necessarily because after the filter the cake is fed into a thermo ventury drier, what are reported there are the actual tons of concentrate bag after drying.
The cost of such Crowe de aeration operation is low as it consists almost entirely of electric power to elevate gold bearing solution to a height of approximately nine meters and power to operate a vacuum pump of 600 700 m3 per hour capacity. In all about 8 kW is involved for the treatment of 290 310 tons of solutions per hour.
gold solution , is routed to the filter plant where the solid and liquid phases are separated. The solid particles are repulped and discard ed on the slimes dam while the pregnant solution is treated further to extract the gold. Rotary vacuum filters are currently in use on the company39;s gold
the size of the leaching plant that would be required as well as reduces the amount of leaching reagents required. Many gold plants use conventional thickening with flocculant addition. High rate thickeners, as well as de watering systems that use cyclones only or cyclones and high rate thickeners can also be used in principle.
This means that the system can generate a high operating vacuum pressure with a much smaller rate of flow in measured in m 3 /h/m 2. The result is up to an 85% reduction in energy consumption compared to conventional cloth disc, drum, and belt filters, and plate and frame pressure filters .
The underflows from the two compartments of the fourth and final thickener are pumped to two 6 x 4 disc Disc Filters. The filter cake is repulped and pumped at high density to tailing pond. Fresh wash water is added to the fourth thickener to make up loss of solution due to evaporation and for solution contained in filter cake.
BoVac Disc filters are modern high performance vacuum disc filters which set new standards with their reliability and cost effectiveness. They are characterized by extraordinary performance, an extremely large filter area and low space requirement. With regard to filtering and dewatering large quantities of suspension, these filters are unbeatable.
The Vacuum Disk Filter consists essentially of a slowly revolving drum, the lower half of whose circumference is submerged in the pulp to be filtered. The filtering medium is applied all around the periphery, which is divided up into a number of separate segments, more or less isolated from one another. The vacuum is applied through the axle bearing by means of a header valve which is so ...
CDF vacuum disc filters with ceramic filter plates are the best solution for filtration of slurries with high con centiation of solids , when it is required to obtain the dry final cake with minimum operational costs, high filtration rate due to a big filtration area.
