Refining Services
Gold Metallics Bullion - dry, directly meltable metallics,
Gold Metallics Bullion - dry, directly meltable metallics, containing less than 20% Ni and no Cd. Casting scrap (gates, sprues, buttons), bars, skeleton scrap, lathe scrap, flake, filings. Contacts on support blades, plates and posts can be processed provided the support is less than 50% of the total mass. Canadian gold coins are not accepted for refining.
Silver Metallics Bullion - dry, directly meltable metallics
containing less than 20% Ni and no Cd, W or Fe. Casting scrap (gates, sprues, buttons), bars, skeleton scrap, lathe scrap, flake, filings. Contacts on support blades, plates and posts can be processed provided the support is less than 50% of the total mass. Canadian silver coins should be reported using the appropriate refining packing slip.
Platinum or Palladium Metallics (Including Dental Alloys) Bullion - dry
, directly meltable metallics, casting scrap (gates, sprues, buttons), bars, skeleton scrap, lathe scrap, flake, filings. Scrap from Dental offices without amalgam (mercury). Radioactive or bio-hazardous materials cannot be accepted.
Industrial equipment
Global producers
The electronic needs of the industrial equipment market are broad,diversified continually evolving and firm competing inthis market face substantial pressure from low cost global producers and new competitors.
CPMR Gold Bar 1 Kilo advantages:
-The CPMR Gold Bar has a very low premium over spot. -The purity, content and serial number of the CPMR Gold bar is stamped directly on the bar making buying and selling safe and easy. -The CPMR Gold Bar is coveted worldwide making it highly liquid and recognizable. -The CPMR Gold Bar is .9999 fine gold and it is one of the most convenient and compact ways to transport your wealth weighing in at 32.15 troy ounces (2.2 lbs).
The method of choice for gold analysis through time has been fire assay.
The basic procedure for fire assay involves mixing an aliquot of powdered sample (10g, 15g, 30g, or 50g are the common sizes used) with soda ash (sodium carbonate), borax (sodium borate), litharge (PbO), flour (baking flour used to add carbon as a reductant), silica, and possible nitre (potassium nitrate)./
Gold and Gold Alloys
The metal gold is extremely malleable. Gold is also ductile and one ounce can be drawn into 80 km of thin gold wire (5 microns diameter) to make electrical contacts and bonding wire. Gold has a Young's modulus of 79 GPa which is very similar to silver, but significantly lower than iron or steel. The purity or fineness of gold in the jewelry is indicated by its karat number.
