Processing of Complex Materials in the Copper Industry
With the gradual decrease in the grade of copper ores being processed copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production while increasing operating costs due to processing the increased amounts of secondary products (slag

Metallic grain structures and microscopic analysis insight
The grinding and polishing process flow for a mirror is as follows Initial coarse grinding is performed on the surface. The surface is gently polished with fine to very fine abrasives until nearly all damaged areas are removed typically using diamond aluminum oxide or colloidal silicon dioxide on appropriate polishing cloths and discs.

5 Things to Consider When Heat Treating MetalMetal
For instance at Metal Cutting we always want to know if the parts we cut will then be sent to a third party for heat treating or annealing. Since parts are made more pliable by annealing inadequate packaging could cause annealed parts to become warped when they are repackaged and sent to you (or sent back to us for additional processing).

Many advantages make electrolytic in-process dressing (ELID) grinding desirable for cutting hard and brittle material with high surface requirements. The self-electrolytic in-process dressing property in ELID grinding is also largely responsible for the shorter wear life and lower forming accuracy of the grinding wheel. In ELID grinding except for traditional mechanical wear the electrolytic
