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.
Dec 18, 2017· Mining waste management: The importance of Tailings Reprocessing Tons of excavated material are extracted every day in mines around the world but only a small percentage contains the wanted mineral. This process is called ore grade. Have you ever wondered where the leftover material goes once the valuable part has been picked out? The answer is as simple as alarming.
The tailings were deposited as a result of over 50 years of mining activities at the site, which occurred up until the late 1980s. Tailings resources at the mine are stated at 3.75Mt at 1.14g/t gold, 0.25% copper, 0.11% cobalt and 80% coal washery grade magnetite. The recoverable value of metal content, in the tailings is over A$700M.
In these cases it may be valuable to investigate reprocessing of the tailings to recover those metals. For historic operations processing may not have been as efficient, resulting in more value contained in the tailings facility. There are also often legacy environmental issues that may be addressed if the tailings are reprocessed.
tailings for road base construction. It has been concluded that mine tailings can provide a substitute for filler materials in pavement. Mine tailings can also be substituted for concrete specimens at up to 9% of conventional concrete by weight. This is applicable to a variety of the minerals found within these tailings.
