To treat cyanide tailing of flotation gold concentrate in Wulaga gold mine by cyclone concentration and mud-removal,then the sand and overflow are filtered by pressure filter and the filter cake are roasted to make acid,again the calcined ores are treated by cyanide leaching of gold. By this way,the total gold recovery rate improves by 5.3% besides annual output of 18 thousand tons of sulphuric acid.
This paper explains the advantage of new type pressure filter in technical design and production practice according to contrasting new type pressure filter with old type in slime pressure filtration production practice.
Examples include on-line measurement of solids distribution in stirred tanks and crystallizers, monitoring the performance of an industrial pressure filter, and flow profile and velocity measurements in a physical model of a catalytic reactor.
Automatic pressure filter operating under optimum conditions
Kinetics of reverse osmosis desalination of aqueous sodium sulfanilate is studied on a laboratory pressure filter unit, in relation to the solution concentration, temperature, and pressure in the intermembrane channel.
The major operational difficulty encountered in pressure filter installations is inconsistent clean separation of the cake from the filter media.
The minimum acceptable respirator is a negative pressure filter or cartridge half-face respirator that is correctly equipped for the hazard.
