  • Sampling/Pilot Plant Crushers McLanahan

    31.05.2018· Sampling/Pilot Plant Crushers are ideal for clients who have applications that require relatively low feed rates but still expect the durability and robust design usually associated with larger crushing machines. Using a significantly oversized crusher to handle the crushing requirements in either type of scaled-down material handling system is not an effective option for a number of reasons, not the least of which is a lack of cost-effectiveness. Dependable, heavy-duty crushing

    Draw two diameters at right angles to each other, and reserving any two alternate quarters, reject the others. Mix; and form another cone, and proceed until a sample is got of the bulk required. This is the usual plan, and all samples should be treated in this way when the stuff is fine enough to fall evenly down the sides of a cone.

  • Assaying analysis of ore samples Waihi Gold

    Fire assay involves adding a ground portion of the solid (or carbon) to a crucible containing a flux. Flux is used to lower the melting point of the samples to ensure the entire sample becomes liquid during firing. The flux contains borax, soda ash, silica flour, litharge (lead oxide) and silver nitrate in various quantities. In the firing stage everything turns liquid and the lead oxide forms into small globules of metallic lead.

    An assay is an investigative (analytic) procedure in laboratory medicine, mining, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity (the analyte). The analyte can be a drug, biochemical substance, chemical element or compound, or cell in an organism or organic sample.
