In the beneficiation plant, the thickener is widely used in the thickening of pulp and tailings, so that the backwater can be recycled and the concentrate is dewatered before filtering. Thickeners can be widely used in the treatment of sludge, wastewater, and waste residues in metallurgy, mining, coal, chemical, building materials, environmental protection, and other industries

The thickener is one of the indispensable equipment of each large-scale beneficiation plant, which is suitable for the dewatering treatment of concentrate and tailings in the beneficiation plant.However, with the continuous improvement of mineral processing requirements, the disadvantages of traditional thickeners are becoming more and more prominent, such as slow settling speed, easy operation and

Jul 13, 2016 How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted

The common thickener underpins the performance of most hydrometallurgical facilities. Thickeners are simple, reliable, effective and efficient-under the right conditions. For the rest of the time

May 06, 2016 THICKENING Phosphate. The slime overflow from the primary cones at 4 to 8% solids is fed to a thickener for water reclamation. The slimes will settle to about 25% solids and are pumped from the underflow to tailing ponds. Special precautions should be taken when impounding this material due to the almost complete absence of sand

Mineral beneficiation is the process of concentration, and was first described in Agricola's famous treatise, De Re Metallica, published in 1556. The earliest ores to be discovered and processed were of such high grade that they did not require beneficiation

As the first step of dewatering operation, thickening operation occupies 9% influences on the whole beneficiation process, and 35% effects on the whole dewatering operation. The quality of thickening equipment will directly affect the result of dewatering operation, and high quality thickener will increase 20%-30% thickening concentration, then strengthen thickening result

Jan 24, 2020 Thickener is the common mineral processing equipment in mineral processing plant, which is widely used in the concentration and dewatering of mineral processing plant.However, in the practical operation, the fault rate of thickener is up to 37%. Therefore, daily maintenance is vital . The daily maintenance includes the daily check, machine lubrication, preventive maintenance and other

May 22, 2019 May 22, 2019 Ultimate Guide About Thickener. The quality of thickener will directly affect the result of dewatering operation, and high-quality thickener will increase 20%-30% thickening concentration,then strengthen thickening result. In the current ore dressing process, most mineral processing plant adopt wet separation process, so the concentrate has

ciation plant 2 thickener underflow (Tailing). Iron ore slimes (−45 micron ~80.0%) generated at beneficiation plant 2 assaying 46.7% Fe, 10.82% SiO. 2, and 4.58% Al. 2. O. 3. have been subjected to various beneficiation studies like cyclone, wet high intensity magnetic separator and flotation to recover the iron bearing minerals

What is mineral beneficiation? Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes

Jan 13, 2017 Thickeners are designed to operate continuously with slurry/water consistently flowing into the centerwell with thickener underflow pumping balanced to maintain a mud bed in the thickener. Key to thickener operational efficiency is the solids must be able to settle 2-4 times faster than the nominal water up flow rate

Swapan Kumar Haldar, in Mineral Exploration (Second Edition), 2018. 13.2.4.3 In-Stream Analyzer and Process Control. Mineral beneficiation, particularly base and noble metals, is sensitive to optimum use of reagents, recovery of metals, and clean concentrate.High fluctuation of feed grade at flotation cells yields loss of metals to tailing.
