Improving flocculation and dewatering performance of
2019-10-1 In this paper the bench and full-scale flocculation behavior of iron ore tailings is investigated in order to improve the dewatering performance of tailings thickeners of an iron beneficiation plant. In the batch settling tests, the effect of flocculant dosage (5–20 g/t solid), slurry solids concentration (3–12 %), pH (4–12), and ...

Beginners guide to thickeners - Outotec
2017-6-16 Simple systems with constant feed can use flocculant pump speed control, more advanced control systems utilize a ratio controller to maintain a constant “grams per ton” dose rate. Unfortunately, fluctuations in ore type can significantly change the dosage of flocculant required and require a feedback to the “grams per ton” constant.

Performance evaluation for selectivity of the flocculant ...
2013-12-14 Increased demand for iron ore necessitates the utilization of low-grade iron ore fines, slimes, and existing tailings. Selective flocculation can be an alternative physico-chemical process for utilizing these low-grade fines, slimes, and tailings. In selective flocculation, the most critical objective is the selection of proper reagents that will make floc of desired minerals. In

Pumping system design challenges for high-density iron
Abstract: Fine iron ore tailings slurry is commonly deposited in tailings storage facilities across the Pilbara region of Western Australia. Many of these mines process ore from a combination of deposits such as Bedded Iron Deposits (BID), Channel Iron Deposits (CID) and Detrital Iron Deposits (DID), mixing the feed to obtain the product under contract.
