  Identifying mine waste materials as economic resources will help support global demand for critical metals, boosting the mining industry during the downturn. All with environmental : Anita Parbhakar-Fox. As shown from the current results, if a 30% recovery is achieved from this 10% copper lost in the tailings, it could mean an increase of about percentage points in the overall recovery, achieving a total of % Cu recovery.

  This paper presents the feasibility of incorporating copper mine tailings (MT) as a partial substitute for cement in the development of concrete. The copper mine tailings used for this study have been accumulating for several decades at the tailings dump of Hindustan Copper Ltd. at Khetri, Rajasthan. Hence, alternative uses of MT need to be thought while keeping in mind that the utilization Cited by: 9. Mine tailings (MT) have been used in previous studies as substitute construction material to recycle waste products, especially in hollow blocks and bricks production and as masonry mortar. This study investigated the use of Philex copper-gold mine tailings (PCGMT) in roller compacted concrete (RCC) production, a mining waste material consisting of finely grinded siliceous particles was Cited by: 3.

The Bureau of Mines studies tailings samples from 11 large-scale western copper operations to determine the potential for recovery of rutile and other critical and strategic minerals. Up to 15 pounds per short ton (lb/st) ti02 was found in these samples; however, only 9 to 44 pct of the tio2 was liberated rutile.

mine the feasibility of rutile recovery from other western copper mines. Eleven companies, some of which wished to remain anonymous, cooperated in this study, submitting a total of 15 flotation plant tailings.

XRD analysis identified quartz, pyrite and gypsum, but no copper minerals, in CLC tailings. Other data, provided by Francisco Sánchez Ruiz (Cobre Las Cruces, S.A.), showed that most (60%) of copper in these tailings was deported in chalcopyrite, with smaller amounts present in covellite (18%), tetrahedrite (%), enargite (8%) and bornite (1 Cited by: As copper tailings appear in ground form, the grading of copper tailings reported by Gupta and Thomas () and Nitish et al.

Davis, G. Sullivan, and W. Lamont UNITED STATES DEPARTMENT OF THE INTERIOR. The achieved copper recovery of 12% for 2 h with tap water, points to the possibility of natural dissolution of copper from the tailings due to the presence of copper oxides or copper sulphate in it.

The Bureau of Mines studied tailings samples from 11 large-scale western copper operations to determine the potential for recovery of rutile and other critical and strategic minerals.

A new flotation tailings treatment process was developed for efficient Cu recovery. • An efficient Cu dissolution was achieved in an H 2 O media in presence of pyrite. The dissolution mechanism of CuFeS 2 has been confirmed to be a multistage reaction. Fe was always co-dissolved with Cu following a linear relation of C Fe = × C Cu.

Over 91% Cu was extracted from Cited by: 6. value than Co. Cu recovery can be done at pH after ferric removal, while efficient cobalt recovery could be obtained at pH values > Mintek previously evaluated the problem of simultaneous recovery of Cu, Ni and Co via RIP [5].

Overall, it seems that there is a potential for the use of copper tailings as a zero-cost, environmentally-friendly additive in concrete, especially at a 5% addition level.
