Are there any national or industry standards for matte copper? Are there any grading standards for the content of various elements in matte? Help needed :$ :$ :$ :$ :$ :$ :$ :$
I don’t think so; there are national standards for rough copper
Everything that enters GB is of commercial grade; do you really expect to sell your matte copper outside as well? The grade of matte and the contents of various components are provided as a reference for your technical staff to optimize operations
There is an industry standard for matte copper: YS/T921-2013. I hope this helps you.
It depends on what kind of furnace is used to produce blister copper
