Our incineration systems allows
us to burn material containing
precious metals with
clean air emissions.
Sweeps Refining
Ship your floor/polishing sweeps, filters, sink trap sludge, rags that may contain precious metals and let the PRO's handle it.
Once your material is safely burned, it then continues to the crushing system. This breaks down the material further to produce a fine powder.
The material is then cooled and sifted through a 75-mesh screen to separate the fines from the metallic tailings. Magnetics are separated from the tailings prior to being sent to the melt area. Blending the fines sample is critical to ensure a homogenous sample for analyzing the material. This is achieved through a large barrel blender, as well as a smaller bottle blender for the sample.
A moisture test is performed to help determine the amount of moisture in the fine’s samples. The fines samples are tested for precious metals using ICP Analytical methods.
Why Use Profiners:
Our Stationary and Rotary incinerators are maintained and inspected regularly to ensure efficiency. Moisture evaluation is performed on every lot to establish the correct value of the material. The lot is then tested via ICP analysis and Fire Assay numerous times on our ISO9001 calibrated balances for settlement.
Tailings – Material from dust that will be melted and assayed to determine content
Atlas – Box furnace for burning dust material that may include floor sweeps and rags
