The production of solid mine wastes is an integral part of the extraction and metallurgical processing of ores. The reclamation of highly reactive mine waste, with low neutralizing potential, is still a significant challenge for the mining industry, particularly when natural soils are not available close to the site. Some solid mine wastes present interesting hydro-geotechnical properties which can be taken advantage of, particularly for being used in reclamation covers to control acid mine drainage. The main objective of this research was to evaluate the use of mining materials (i.e., tailings and waste rock) in a cover with capillary barrier effects (CCBE) to prevent acid mine drainage (AMD) from highly reactive tailings. The first part of the project reproduced in this article involves context and laboratory validation of mining materials as suitable for a CCBE, while the companion paper reports laboratory and field results of cover systems made with mining materials. The main conclusions of the Part 1 of this study were that the materials studied (low sulfide tailings and waste rocks) had the appropriate geochemical and hydrogeological properties for use as cover materials in a CCBE. Results also showed that the cover mining materials are not acid-generating and that the LaRonde tailings are highly reactive with pH close to 2, with high concentrations of metals and sulfates.

Column experiments investigated the stabilization of waste rock from Ljusnarsberg mine in Kopparberg, Sweden. In order to inhibit the generation of acidic leachate from the waste rock, biosludge and a Ca carbonate – rich residue from the paper industry were mixed with the sulfidic mine waste. The results of the column experiments indicate that the stabilization of the waste rock with the reactive amendments succeeded in maintaining a near – neutral pH in the waste rock leachate, compared to a pH 3 leachate from untreated waste rock. Copper and Zn concentrations in leachate from the untreated waste exceeded 100 mg/L, while these metals were detected at concentrations less than 0.1 and 1 mg/L, respectively, in the leachate from the treated wastes. This study indicates that the stabilization of acid – generating waste rock with biosludge and Ca carbonate residues is effective in preventing the generation of acid mine drainage; the treatment is expected to continue until the reactive amendments are exhausted.

Rock Characterization

Acid mine drainage is one of the significant negative impacts of  mining activities that can result  in environmental degradation. Waste rock is  mine waste that is found in large quantities and can produce acid mine drainage (AMD). This study aims to identify  waste rock which has  the potential to generate acidity (PAF) and do not generate acidity (NAF) in the Barani and Ramba Joring pits and the application of the encapsulation model in  tailings dams. The research method with the encapsulation model is a simple method designed in tailings dams to encapsulate the PAF with the NAF. Rock characterization and geochemical analysis will result in the rock being classified  as  PAF and NAF in both wells . The data used for this study are drilling data (cutting) data that include rock lithology and chemical quality (NAPP and NAG) data. The results identified that the PAF was dominant relative to the  NAF  both wells  and the waste rock in the Barani pit was at a  higher risk of producing acidity than the Ramba Joring pit. Measurements of oxygen diffusion and surface water quality indicated that encapsulation of waste rock in the tailings dam may  prevent the formation of acidic mine drainage
