Equipment for solid-liquid separation is an essential part of our mining plant.
Traditional solutions such as gravity thickeners, settling ponds and filter presses are often associated with high costs, poor efficiency and/or environmental issues.
Is there any new technology plant operators are using for the solid-liquid separation?
How do you optimize this process?
Please share your ideas and any innovations in the field.
There is a new technology using a vey innovative polymer process that is in commercial operations currently in Ukraine in Waste Water treatment Plants that through simple injection of the polymer and just gravity flow - separates the TSS and solids from the waste water very quickly and dries the separated solids 10 times faster than currently used polymers. All this through just gravity flow and drying beds. It has proven to continue to dry the solids even with snow and rain on the separated solids in the drying beds. Go to: www.gc-solutions-inc.com
I agree with Maher Louis. De-sander Hydrocyclones are the usual equipment used for lolids-Liquid separation in the oil industry and can be well exported to the mining industry.
The solid content in the treated water can be easily reduced to particles not exceeding 25 micron (typicaqlly equivalent to about 98% efficiency in solids separation). Is it enough for your use?. The hydrociclones and the paired tanks are typically skidded in a rather small arrangement and available at a very reasonable price.
I am not selling any equipment like that, but I license the design to the fabricators, thus reducing the selling price to the very minimum.
Now a days number of technologies are available in market technologies for solid/liquid separation. In addition of the technologies you have described, you can find rainage tables, centrifuges, belt filters, disc press, screw press, etc.The most widely used conventional filter technology includes filter presses, vacuum filters, centrifuges, low-pressure automatic pressure filters and high-pressure or mechanical expression automatic pressure filters.The process depends on your need regarding the final dryness (thickening or dewatering?), reagent consumptions, manpower requirements, centrates qualtity, CAPEX, etc.
NEW FILTER TECHNOLOGYRegards,The focus for the design of the new high-pressure APF was to develop very effective filtration technology using mechanically simple and robust equipment available in a wide range of capacities.
A very effective concept, less expensive, efficient, design calculations are available everywhere, is the cyclone. We manufacture them, if you would like to refer to us (clairmonte.com). Thank you.
if you speak about "not enough efficiency", supposed fine after treatment is required.
Importand think for understanding what you need is kind of mine (coal, gold etc) this important because water quality will be different.
I had some experience with ultrafiltration of mine water after sedimentation pond on coal mine. At this moment few systems are working in CIS territory.
There are numerous technologies you can utilize to increase solids content and to bolster efficiencies associated with your solids liquid separation equipment.
DAF's, gravity belt thickeners, and gravity clarifiers are often very effective thickeners, especially when coupled with a flocculant or coagulant to aid in the dewatering.
Belt filter press, screw presses, and centrifuges are all great ways to make very high solids content cake but require significant sludge conditioning and either energy, manpower, or capital to implement.
I would love to discuss this more with you. Feel free to message me
Dear John, you have many technologies for solid/liquid separation. In addition of the technologies you have described, you can find rainage tables, centrifuges, belt filters, disc press, screw press, etc.
The choice deponds on your targets regarding the final dryness (thickening or dewatering?), reagent consumptions, manpower requirements, centrates qualtity, CAPEX, etc.
