Bornite is easily recognized because it tarnishes to iridescent shades of blue, purple, red, green and yellow. It is commonly called "peacock ore" or "purple copper ore" after these iridescent colors. Upon surface exposure, bornite will weather to chalcocite or other copper minerals. Bornite is a popular and fast-selling mineral specimen at museums, mineral shows, and tourist shops. However ...
Alternative mining methods were also investigated as a means of reducing stress concentrations and removing workers from hazardous areas. Collaborative research was conducted with four underground metal mines located in the western U.S., two universities, and multiple industry experts. In conjunction with this research, comprehensive backfill design guideline development was advanced for the ...
