Jensen's refining service |
| |
 |
Your scrap
arrives at Jensen, usually by express carrier,
and is safely locked away until its turn to be
logged-in. |
| In the
log-in department, your scrap container is carefully
opened, and the contents are unpacked and precisely
weighed. The entire process is filmed under two
video cameras (birds-eye view and close-up view)
to provide verification of accuracy and security.
The video will be kept on file until your settlement
is finalized. |
 |
 |
After
video log-in, a "processing schedule" is created,
and it stays with your lot throughout the refining
process to ensure that all the pertinent information
about your lot is documented and recorded. This
includes checking in, and reweighing the lot before
and after processing. |
| Most lots
contain a mixture of materials, and require initial
processing in the foundry. This is where a professional
refining technician separates the "metallics"
from the "non-metallics" contained in
your lot. Depending on the amount of initial material
that is non-metallic (vacuum bags, for example),
the lot may first be incinerated. |
| After
incineration, your lot is placed in a crucible
with powdered borax and soda ash, and loaded into
a natural-gas furnace and melted. This is when
the "metallic" and "non-metallic"
separation occurs. |
 |
| After
the metallic portion of the lot is obtained, your
lot is melted again in an electrical induction
unit to ensure a homogenous composition for testing.
Homogeneity is very important for Jensen to retrieve
an accurate sample of your lot. |
 |
Once your
lot is thoroughly melted, the sampling process
begins. A "vacuum pin-tube" is inserted
into the molten metal. A sample of the metal is
sucked up into the tube, where it quickly hardens.
There is no better way to obtain a homogeneous
sample of scrap material. |
|
Now it's time to check the elemental composition
of your sample during the "assay" process. Jensen
employs many analytical techniques, including
"fire assay" and "wet" chemistry" to determine
the content in a scrap lot. |
 |
 |
Once the
assay process is complete, all the information
about your lot is compiled and reported to you.
In most cases, Jensen will be ready to settle
your lot within 2 weeks after your lot is logged
in. |
| We hope
you've enjoyed this tour. If you have any questions
about our refining process, or how to arrange
for an assay of your material, please call us
at 800-243-2000. We'd be happy to assist you!
