Carbide Grinding Sludge Value
Carbide Grinding Sludge Value
1. Carbide sludge is worth money based on the amount of tungsten in the sludge. So tungsten from tungsten carbide in the sludge is a positive. Iron from steel grinding is a negative. I believe the limit they’ll accept is 10% iron.
The way it works is that you send us a sample of the sludge, maybe a quart. We have that analyzed and that determines the value of the sludge.
They do subtract for any moisture in the sludge.
Here is an example from one customer.
Sludge:
517 lbs Gross
– 44 lbs Tare (7 buckets/skid)
473 lbs Net Wet Material
– 24 lbs Oil & Moisture Removed ( 5%)
449 lbs Net Dry Material
x 46 % Tungsten Contained
207 lbs Net Dry Tungsten
Then the 207 pounds is multiplied by whatever the current market is.
2. The tungsten market came down a bit and now it is flat by some indices and going back up by others. Following is a link to a page with free charts on tungsten.
