Prediction of barite recovery and grade by multiple linear

As a result of experiments, a barite concentrate from the barite tailing containing 38.40% BaSO4 was obtained with 92.55% BaSO4 grade and a total barite recovery of 78.41%. MLR studies also showed that there were good correlations between the experimental results and predicted values (R 2 values of 0.928 and 0.853 for the Ocean Management, 8 (1982) 29-49 Elsevier Scientific Publishing Company, Amsterdam Printed in The Netherlands An Examination of Metal Inputs to the Southern Beaufort Sea by Disposal of Waste Barite in Drilling Fluid R.W.

Sustainability Free Full-Text Superiority of Filtered Tailings

In order to evaluate the superiority of a filtered tailings storage facility (FTSF) to conventional tailings impoundment in the southern rainy regions of China (SRRC), the tailings slurry leakage and pollution accident occurring at the wet tailings dam (WTD) of Yinshan were analyzed, the properties of the tailings were tested in a laboratory, and the Barite is ubiquitous and known to incorporate 226 Ra through the formation of a solid-solution. In U mining mill tailings, barite is one of the dominant sulfate-binding minerals. In such environments, sequential extractions are generally used to identify the U- and 226 Ra-binding phases and their associated reactivity.

Barite resources, production and recovery using froth

The tailings were composed of barite, quartz and carbonates minerals (e.g., calcite, dolomite). When the flotation reagent scheme included 200 g/t of SS and one drop of Aerofroth 76 in additional to the 700 g/t of NaOl, barite recovery was improved to more than 80 % ( Deng, 2019 ).Less investment, significant social and economic benefits Under normal circumstances, the production cost of tailings dry discharge is about 3%-10% higher than that of tailings wet discharge, but in terms of the construction cost of tailings storage facilities in the early stage, tailings dry discharge is more expensive than tailings wetDry Tailings Processing Solution Needs To Be Implemented

Recovery of lead and barite from the abandoned Ichmoul

Thereafter, this mining site was known as an artisanal mining. This work focused on the recovery of lead (Pb) and barite (BaSO4) that are present in Ichmoul mine wastes. The results of mineralogical, physical and chemical characterizations revealed the presence of 3.82% lead and 49.60% barite in waste rocks, and 62.73% barite in tailings.Based on research carried out at 67 tailings dams in Spain: (1) tailings dams contain alternating sedimentary layers with contractive and dilative geomechanical behaviours; (2) tailings saturate quickly but drain more than 10 times slower due to the high-suction capacity of the porous sediments (2–300 MPa); and (3) over the long-term, a How to Prevent Flow Failures in Tailings Dams Springer

Dry Stack Tailings: An Alternative to Conventional

The dry stack tailings minimize the complexity of permitting and minimize the potential of public concerns from nearby communities. Drip-free, dewatered cakes discharge from a Filter Press into a pile. Dry stack tailings management is becoming a more accepted practice due to the recurrent disasters seen with older, non-thickened and even Application to the treatment of barite or copper ore tailings has also been reported (Castillo et al., 2019; Deniz, 2015; Nasser and James, 2006).

Sustainable Management of Thickened Tailings in Chile and

The “Thickened Tailings Disposal” (TTD) technology produces a high density mine waste that allows for the storage of this material without the need to manage large slurry tailings storage facilities (TSFs) and large dams. TTD has been applied considering site specific conditions of Chile and Peru, such as extreme climatic The mobilization of Sc and U is more sensitive when the tailings contacted the saline solutions. However, the values are quite similar, following the same changes with time for the two saline solutions tested. The maximum cumulative percentages for Sc are 0.002% in C W, 0.245% in C S1 and 0.252% in C S2.Behaviour of flotation tailings from a rare earth element

Metals Free Full-Text Submarine Tailings in Chile—A

This review aims to understand the environmental impact that tailings produce on the land and marine ecosystem. Issues related to flora, fauna, and the environment are revised. In the first instance, the origin of the treatment and disposal of marine mining waste in Chile and other countries is studied. The importance of tailings’ valuable elements is analyzed The samples were ground in a porcelain ball mill and then dry-screened to obtain particles separately and dried afterwards before being weighed. For artificially mixed minerals flotation, the concentrates and tailings were assayed (Chinese standards GB/T 5195.1-2006) to acquire the grades of fluorite and barite, before calculating theFlotation studies of fluorite and barite with sodium
