Iron tailings: the iron tailings discharge from iron ore plant is in large amount, fine size and different types, and complex property, so Xinhai use the process of magnetic separation, flotation, acid leaching and flocculation to recover iron. Gold tailings: Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings.
New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources.
The Global Mining Guidelines Group (GMG), in collaboration with Cambrian College, has developed a landscape of tailings management activities in the mining industry (view it here).This study of guidance documents, project initiatives and standards from around the world provides an understanding of existing practices and initiatives covering mine tailings throughout the global mining
Extraction of valuable metals from tailings dumps (or residues or low grade stockpiles) traditionally regarded as waste, has long been researched by metallurgists. A number of developments in mineral processing technology have combined to make the retreatment of numerous tailings dumps a profitable proposition.
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.. The extraction of minerals from ore can be done two ways: placer mining, which

Aug 10, 2018· Sulfuric acid is sometimes produced when water interacts with tailings, or it can be a by-product of ore processing. As a result, highly acidic water leaks from the tailings and disrupts aquatic life downstream. Tailings from copper and uranium mining often produce measurable levels of radioactivity.
By doing this we obtain a lower processing operation cost. The Parral project has a 60 percent value in silver and a 40 percent value in gold. This makes it is primarily a silver project. The process begins when we employ contract trucking, pick up the tailings, drop them at our new site, then mix them with cement to make a paste.
Aug 03, 2020· Alfa Laval P3 solid bowl centrifuges help mining and mineral processing companies eliminate many of the problems associated with tailings dam operations and filtration technologies.
“Hydraulic mining of tailings dams and waste represents a strong future for Australian coal, not just for flood recovery, but for the ongoing profitability and environmental sustainability of the industry,” said Ross Garling, Managing Director of Hydraulic Mining Solutions.
Jan 26, 2015· Both mine dumps and tailings piles are mentioned above, so I don't think this is about mill tailings. So, you are talking about mine dumps or mine tailings that contain good values and are worth processing. These dumps can contain all sorts of large waste rock and trash. Here's a question...
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
Tailings are finely ground rocks and other mineral waste as a result of mineral processing. Due to the way minerals are processed, tailings can contain concentrations of processing chemicals. This can make mine tailings an environmental concern, so

Nov 25, 2019· Using these toxic chemicals to release fine gold ores from rock is a process that has existed for over 100 years. Mr McCulloch explains that, beyond the risk of chemical exposure facing workers directly involved in mining operations, these toxic chemicals are often also expelled into tailing dams with waste water from the extraction process.
Reprocess tailings. Really? Yes, really. If the technology exists today to remove up to 90% of water from mine tailings and, if a mining company is going to make that investment anyway to secure its future operations, then frankly, it is irresponsible not to consider reprocessing the tailings
