Coal and Coke. Since the founding of Revere in 1980, and many years before that for some of our key people, we've been helping clients design, build and install bulk material handling systems for the coal and coke industry. We've worked underground and overland; we've designed short-distance systems and others that stretched for miles.

Sluicing. It is a process of moving or channeling the slurry to the sluice boxes or other places. Educing. It is the process that introduces the slurry to an enclosed circuit. For example, in gold hydraulic mining, the rebounding water stream and mineral fragments will go to sluices, making the gold settle behind and washing away the lighter waste.

Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth. Open-pit mines are used when deposits ...

The adsorption of As (V) by some natural Fe oxyhydroxides and clay minerals and synthetic Al (OH) 3 and FeOOH has been studied. The results show a very high As (V) adsorption capacity on both synthetic Al hydroxide (122 mg/g at pH: 5) and Fe oxyhydroxide (76 mg/g at pH 5). This adsorption capacity is pH dependent and shows maximum values at ∼pH 4.

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

In-situ mining (also called in-situ leaching or recovery) is a mining method that's used to obtain minerals like uranium and copper through drilled boreholes into a deposit. In-situ mining works by dissolving naturally occurring minerals that are in a solid state. A leaching solution is pumped into the boreholes where it makes contact with the ore.

It all begins with site selection. Spinks has control of the clay reserves under approximately 25,000 acres of land, so this selection is not a trivial task. Once a property has been selected, a grid is laid across the property in 150-foot squares. Each point on this grid is drilled. If clay is present, samples are taken every two to three feet.
