Mine tailings containing metal sulfides could have an important environmental impact if control strategies imposed to prevent the oxidation of sulfide exposed to weathering conditions are not established. Natural oxidation of metal sulfides may generate the so–called "acid rock drainage" and "metal leaching" (ARD–ML). The ARD–ML is often ...

Acid mine drainage detrimentally affects thousands of surface watercourses throughout the world and costs tens of millions of dollars annually in site remediation expenditures ...
Acid mine drainage can be released anywhere on the mine where sulfides are exposed to air and water — including waste rock piles, tailings, open pits, underground tunnels, and leach pads. Acid drainage is often marked by "yellow boy," an orangeyellow substance (visible in the photo on this page) that occurs when the pH of acidic mineinfluenced water raises above pH 3 (approaching more ...
He recently provided technical support to Sedgman and New Century Resources for the reprocessing of historical tailings. Peter Scott ... material characterisation, leachate control and fate transport modelling, baseline investigation for assessing and monitoring leachate development from mine waste, rehabilitation and remediation design for Acid Metalliferous and Saline Drainage (AMD) in mine ...
Tailings reprocessing technology means higher demands on mining enterprise, especially in tailings test, technological innovation, energysaving and capital investment. For the majority of mining companies, they can't afford these huge capital investment and strict technical requirements.
· Doyon mine (Quebec) explores the possibility of reprocessing concentrator tailings by environmental desulphurization, and using the desulphurized tailings as cover material for the existent tailings ponds to prevent acid mine drainage (AMD) generation. A laboratory study using instrumented columns was undertaken to evaluate the effectiveness of monolayer covers made of desulphurized .
Mine Drainage Chemistry ... Waste Rock Storage Facilities Landfills and Solid Waste ... Reprocessing of historic tailings impoundments can create shared value between the mining company and the nearby communities when the additional minerals are extracted from legacy impoundments and the new reprocessed tailings are then placed in modern and engineered facilities compliant with current ...

· Untreated acid rock drainage leads to serious contamination of large areas of land, as well as surface and ground water resources. The seriousness of the problem has led to major research efforts to find solutions. However, effective ARD treatment and prevention solutions have eluded the scientific community over the past decades. This paper presents a detailed review of the current state of ...

· Hard rock mines have significant effects on the territories where they operate, through both infrastructure construction as well as resource use. Due to their extractive activities, these mines store large quantities of wastes at the surface, which can be both physically and chemically unstable. Reclamation aims to return a mine site to a satisfactory state, meaning that the site should not ...
Reprocessing flowsheets for copper mine tailings in Chile were developed and costs and revenues of possible products from reprocessing were examined for a rough economic assessment. Standard cost models with capex and opex for flotation, leaching, and magnetic separation were adopted to the needs of tailings reprocessing. A copper tailing (around 2 M t) that also contains magnetite was chosen ...
