To compare the effects of copper tailings on strength and strength related properties across two concrete classes, two series of concretes with 0.57 and 0.50 water-to-binder ratios are used. For each series, three mixtures incorporating copper tailings at 0%, 5%, and 10% addition levels by mass are prepared.
Tailings basin water, like other water on the site, will be in the neutral pH range. Many years of laboratory testing has demonstrated that these tailings will not generate acid. The use of the existing tailings basin greatly reduces the environmental disturbance of the new mine.
Nov 28, 2016· Copper mine tailings ponds are encircled by soft, sometimes disturbingly soluble earthen dams that are supposed to contain the liquid slurry forever. These dams contain millions of gallons of mine waste that has the consistency of slime. Each pond is an environmental disaster waiting to happen.
Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings.
The tailings properties, tonnage and site topography dictate the type of transportation system required to manage the tailings both cost effectively and efficiently. The types of tailings transportation systems used today are as follows:

Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared to
Every copper/nickel liquid tailings pond holds the 99.8% mine waste plus the liquids that is used to pipe the dissolved powder from the processing plant to the pond. Every copper/nickel sulfide mine in the history of mining has leaked/leached poisons into the groundwater, onto adjacent lands and into the downstream environment.

The Klondyke Tailings Project WQARF (site) ... From the 1870s through the 1950s, lead, zinc, copper, silver, and gold mining was conducted in the Klondyke area of the Aravaipa Mining District. In 1948, the Athletic Mining Company constructed a flotation mill next to Aravaipa Creek that operated until about 1958 and generated, in part, the ...
