THE UTILIZATION OF COPPERNICKEL TAILING INTRODUCTION Though several methods exist for the possible recovery of the copper and nick'el in a Duluth gabbro ore, it appears that concentration of the sulfides by flotation 'followed by smelting offers the most realistic approach. The combination of these processes will of necessity be a large

Tungsten Copper Alloy Cu + W

Consisting of pure tungsten (W) powder suspended in a matrix of copper (Cu), these alloys are known for good thermal and electrical conductivity, low thermal expansion, and resistance to erosion from arcing. Thus, they are often used as electrical contacts, particularly in high voltage applications.
