2021-5-29 Again the addition of polymer aids in the separation and thickening process. The disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry cake which is sent for pelletizing. This process allows ore of very low magnetite content to be processed into a high quality product. Tailings

Selective Separation and Recovery of Valuable Metals

2019-4-16 Many tailings are removed by flotation, which improves the treatment efficiency of separation and recovery of precious metals from the anode slime. However, the tailings inevitably contain a certain amount of rare and precious metals, such as selenium, tellurium, silver and gold.

Recycling mine tailings in chemically bonded ceramics

2018-2-10 Tailings’ characteristics markedly depend on mineralogy of the ore deposit and the refining method selected. One feature typical for tailings pond is grain size differentiation. Sand and silt rich layers alternate throughout tailings bed (Parviainen et al., 2012, Heikkinen and Räisänen, 2008).

Tailings Pond - an overview ScienceDirect Topics

In 2009, journalists reported on damaging effects to humans and the environment from REE mining and separation. Hilsum reported from Baotou, where tailing ponds were full of acid and chemicals ( Hilsum, 2009 ), and Bradsher addressed southeast Chinese mining of ionic clays in which REEs were mined with primitive and nonsustaining extraction methods by draining acids on soil to dissolve REEs.

Recovery and Purification of Tin from Tailings from

A concentrate obtained from mining tailings containing mainly cassiterite and columbotantalite was reduced for the production of tin metal. The compounds CaCO3, Na2CO3, K2CO3, and borax were used as fluxes in the pyrometallurgical reduction smelting process, and graphite was employed as the reducing agent. The greatest recovery of Sn (>95%) was obtained when using CaCO3 as the flux; the purity ...
