  • The application of direct smelting of gold concentrates as an alternative to mercury amalgamation in small-scale gold mining operations in Ghana

    Mercury is used in small-scale mining to amalgamate gold particles, facilitating their separation from heavy sands. The negative environmental/health-related effects of mercury in mining communities in Ghana and other countries have generated research interest into development of safer alternatives. This study tested direct smelting as an alternative to amalgamation. In laboratory investigations, ...

  • Reducing Mercury Impacts in Small-Scale Gold Mining

    Despite knowing full well the dangers of mercury, millions of small-scale gold miners across the globe continue to use the metal to separate gold from ore - usually because they have little other choice. The mercury is mixed into ore and combines with the gold in a compound that can easily be scooped out and squeezed into a small bar of amalgam. This is then burned so that the mercury evaporates, ...

  • Determination of Ultra-Trace Mercury Vapor Levels from Industrial & Military Metal Components

    For many years, scrap metal reclaimers did not separate the materials containing mercury from other metals. Such things as mercury switches, dental amalgam, thermometers, and refining wastes from copper, gold and silver were processed along with the typical industrial metals. The result is that a significant portion of the Ferrous and non-Ferrous metals and alloys used today contain some metallic ...

  • Cart-Based Organics Collection. Citizens Drive 65 Percent Diversion System

    For better or worse, citizens opposing waste management projects usually end up being labeled as NIMBYs — not in my backyard. This could have been the case in Halifax, Nova Scotia but instead, the citizens took their opposition one step further, basically taking the design for an acceptable waste management system into their own hands. In the process, they laid out the foundation for an ...

  • Binary vs Quaternary Pumps

    How is a Gradient Created? Any liquid chromatograph is an amalgamation of a certain set of components that delivers to the scientist a monograph of the sample they are analyzing.  Traditionally, an LC system consists of a pump, an injector, a column heater, a detector and even more commonly these days a mass spectrometer or mass detector.  In ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
