  • Magnets: A viable alternative to flotation for sand producers

    Introduction The basic rudiments of mineral beneficiation have not changed for many years. The techniques have been improved, but are still essentially the same, using either a materials weight, density, shape or magnetic susceptibility to enable separation. For removing impurities from non-metallic minerals, such as silica sand, typical methods include Flotation, Gravity and Magnetic ...

  • Compliance with the RMP Rule at a Waste Management Facility

    A waste management facility typically treats, stores, and disposes chemical wastes that contain chemicals listed under 40 CFR §68.130. After a thorough evaluation of the existing chemical inventories, it is determined that this facility is not subject to the Risk Management Program rule based on the exemptions given in the rule for the de minimis threshold quantities. Due to the uncertainties of ...

  • The environmental pyramid: a new way to deal with solid toxic waste

    Our society produces large volumes of solid waste, including toxic chemical waste. For toxic solids, the current disposal practice is to dump them into isolated, lined pits, and cover them with a water-impermeable layer with a soil layer on top. Such waste deposits require 'eternal' control and monitoring, because they eventually do leak, contaminating the surrounding soil and groundwater. Here, ...
