The company owns the patented BACOX bioleaching technology. This technology is used for the processing of toxic, arsenic-laden mine tailings. An added benefit of bioleaching, in addition to stabilizing arsenic and capturing heavy metals, is that it oxidizes sulphides in mine tailings, thereby eliminating a major source of acid mine drainage.
The Company plans to continue its ongoing efforts to identify, evaluate, and potentially acquire large sources of quality diamond tailings to enhance its ongoing growth strategy. Diamcor has extensive experience, and a proven track record, in the mining and recovery of diamonds through the processing of kimberlite tailings.
Mine tailings' size and composition depends on the mining method. For hardrock metal mines, tailings are usually a very fine mud or powder, which is left over after ore is crushed and valuable minerals are extracted from it. Tailings may also contain chemicals used for mineral extraction.
Once processing is complete up to 40% of the mine tailings can be diverted to a paste plant where it is mixed with cement and used as backfill material for underground mine voids, which reduces the volume of tailings delivered to the tailings storage facility. We utilise the …

Gold Tailings: Hazards and Opportunities Investing News Network - October 4th, 2015 Tailings from gold mining operations can pose a threat to the environment and health of nearby communities.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
This program facilitated the cleanup of 15 million cubic yards of uranium tailings at former uranium mill sites in nine western Colorado communities. Because much of the cleanup is complete, the focus has shifted to primarily "Post-UMTRA issues," or the discovery of new uranium mill tailings material by private citizens, utility companies or local governments.
We have been extensively involved in the permitting, design, operation and closure of mine tailings, mine waste and associated water disposal/management facilities since 1974.

Thickened tailings can be mixed with cement and used in construction or as backfill in underground mines. Now, some mining companies are figuring out ways to turn tailings to profits with novel reprocessing technologies to extract valuable metals from the waste.
historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re-
Dec 18, 2017· Thanks to the progress in technology, companies are starting to care more about mining waste management by reprocessing tailings to increase their value.

Traditional tailings management practices do not align with ever-increasing demands of mining and mineral processing companies. From environmental concerns rooted in disastrous tailings dam failures, to shrinking tailings storage facility footprints due to growing production levels, your tailings management process must be built with an infrastructure that's minded for the future.
Members of the GHD tailings team are active in governance and research in the mining industry and is represented on a number of local and global technical committees, including the International Commission on Large Dams (ICOLD) and the Australian National Committee on Large Dams (ANCOLD).
