Mineral processing equipment in the wastewater treatment should take the
physical and chemical the right way, because the wastewater content is complex,
and the amount of waste water will be relatively large, the first design to take
appropriate measures. At present, most of the beneficiaries of the mineral
processing equipment in the treatment of wastewater treatment or the use of
tailings self-purification method, or the use of coagulation sedimentation
approach to meet the requirements of a large number of customers, our company as
far as possible with easily degradable foaming agent Instead of the stability of
the good pine oil, and the treatment of mineral processing equipment in the
water as much as possible to return to use, broken a small amount of waste water
using coagulation sedimentation, biodegradation, oxidative decomposition,
electrodialysis, reverse osmosis and activated carbon adsorption Processing.
[1] sedimentation method precipitation. - (gravity settling) is the use of
suspended particles gravity, when the gravity exceeds the role of their inertial
force and viscous force, the particles began to settle. Gravity test drop is the
simplest and most widely used method of precipitation in mineral processing
equipment. It is used in concentrating and clarifying concentrate, tailings and
slime during the sedimentation process. The method is also widely used in
wastewater treatment of mineral processing equipment The
[2] floating method precipitation. - (floating method precipitation) the
use of buoyancy in the water or oil and water separation process called floating
method. It is the most commonly used method for the treatment of fine-grained
materials in mineral processing equipment. It can be floated by using natural
floating, or it can also use air or other gases as a carrier to reduce the
proportion of fine-grained materials in the dressing equipment.
[3] filter precipitation - (filtration precipitation) so that suspended
solids through the porous material, to achieve solid-liquid separation process
called filtration is called filtration precipitation. Filtration can be divided
into two categories: filter cake and clarify the filter. Filter cake is a solid
suspension in the filter material on the surface, in the form of cake was
blocked, the filter cake has been formed with the filter together, continue to
retain the later suspended matter. Two: clarification filter, also known as
granular layer filter, is sand, anthracite, garnet and other granular materials
for the filter material, suspended particles in the granular layer of the
surface and the internal gap was left to get clarified filtrate. Filter cake is
used for solid-liquid separation with higher volume concentration (greater than
1%). The main purpose is to increase the solid concentration and reduce the
water content. Clarification Filtration applies to thin suspensions (less than 0
0%) for the purpose of obtaining orange water.
