NEW TECHNOLOGY MAKES WET MINERAL AND ORE MILLING

Ores and minerals in their natural state often contain water. As a consequence, special technology is needed to mill materials of high water content. For the most part, this situation requires milling oper- ations to utilize ball mills while adding water in order to produce a slurry. Unfortunately, this method of removing water requires a considerable expenditure of energy. This paper will

Mineral processing Wikipedia

The particles pass over the screen while the water passes through the apertures in the screen. This process is only viable for coarse ores that have a close size distribution as the apertures can allow small particles to pass through. Sedimentation operates by passing water into a large thickener or clarifier. In these devices, the particles

Uranium Mining and Milling Wastes: An Introduction

Considering the actual period of time the hazards from uranium mining and milling wastes persist, these regulations are of course only a compromise, but they are a first step, at least. Regulations for the protection of groundwater were not included in the initial legislation; they were only promulgated in January 1995. Last but not least, public involvement is given an important role in
