Technicians
Often working from very early to late at night, meeting the deadlines of the client, performing with a dexterity finesse and artists eye the Technician is the un-sung hero of the profession.
With more and more work being out sourced to the Far East the Lab has to be comfortable with not only the refining company used but also to make sure that maximum return is a priority.
D-MMEX is proud of our Lab Client portfolio. It is not large but extremely loyal to us and we take each and every one of these relationships very seriously.
In addition to Failed Crown and Bridgework (detailed in the Dentist page) we handle the following materials.
The trimmed work from crown construction is gathered by The Lab and should represent the highest return of all Lab Waste. These grindings and other high value material such as Casting Machine Flashings are melted down to form a bar. Prior to the melt we will run high strength magnets to remove pins, burrs etc from the mix thus ensuring a clean melt.
Collections of floor sweepings and Central Suction Dust are treated differently to the above. Invariably they are of a higher volume of material yet lower density of value. To process this type of material the items are placed into an oven and burnt down to an ash. Once cooled this ash is raked for any oversize material and then blended in a bore mill. (This is a mixer where ball bearings will break down the material into small particles of fine dust ). Once blended the dust is sampled by taking representative grabs from all four quarters of the powder. The assay itself is performed by acid dissolution of the powder sample to determine the precious content
Most of these items are pure 99.9% and are tested and purchased without need for processing.
It is amazing how the fibres of a carpet can capture value. It is a little pot luck when burning a foam backed carpet as to what may be recovered. If the vacuum has been run over the carpet then it is likely that the value would be in bags if retained. Yet in 2006 (when prices were much lower) one carpet that had been down for 20 years returned over $22,000.
