Cupellation is the last
and most important step in fire assay process and as such, the
quality of cupel is extremely crucial.
During cupellation, the
lead is oxidized to litharge (PbO), most of which is absorbed
by the cupel. Gold, silver, platinum and other precious metals
form a bead in the cupel. The bead is subsequently treated to
determine its precious metal content .
Cupels are typically made
from magnesia MgO (sometimes mistakenly referred to as
magnesite), bone ash, Portland cement and other
materials.
Typical cupellation
furnace temperatures in gold and silver assays are *******0°C,
but can vary with technique, air flow volume and cupel
material.
Yosion aims to manufacture
cupels with followings:
Robust mechanical
strength.
Not affected by
atmospheric changes.
No spitting of
lead.
Rapid absorption of large
quantity of litharge.
Free from cracking and
pitting.
Beads are easily
removable.
Perfect uniformity of
quality.
Reduced tendency to
freeze.
Consistently low
losses.
Regularly tested in our
own assay lab. Manufactured with unique blend of Magnesium Oxide
and special fluxing ingredients.
Available sizes are: 6A,
7A, 7AS, 7AL, 8A and 9.
Customized sizes
and services are also available.
