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.
We have experience in Greenfield and Brownfield operations and frequently perform trade-off studies to determine the best technical/economic solution for the mine, with particular emphasis on water recovery and life of mine planning.
Apache Mill Tailings USA, Inc. is a precious metals mining company specializing in gold, silver, copper and high value, rare earth minerals reclamation recovery. To maximize profits, accelerate project success and reduce risk, we work with above ground mine and ore mill tailings deposits.
Does anyone have experience with the recovery of gold from calcined tailings? The material is the waste product from an Edwards roaster. The host ore is arsenopyrite - very refractory. Normal cyanidation (at elevated temperature levels) only recovers 30% of the gold.
Joining together these units make possible to develop an appropriate flowsheet whose objective is to recover gold and the precious metals present in the ore. Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit.
Feb 28, 2014· The Organisation's long-term strategy is to improve gold recovery so that, in future, zero gold is returned to tailings deposition facilities; and to grow its reclamation business by: • The use of technology and continuing R&D • Acquiring additional surface resources (Gold Dumps) • Using existing expertise and skills to expand into the ...

Tailings are the product of processing ore to recover the contained metals. After extraction from the mine, the ore is crushed and subsequently ground to a particle size that allows for the liberation of the metals from the host rock. Most mineral deposits are composed of many different minerals, some of which contain metals.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.
