Mine. Within the ore pile storage area, there are currently two small ore stockpiles. The ore pile storage area is located north of the mill/processing area. Each of the two ore stockpiles covers an area of less than 1,200 square feet. The ore piles are covered with tarps to protect them from wind and rain. These ore stockpiles are temporary ...

Anyway, if this is actually showing gold, it seems like a very quick test for suspected gold ore. I also tried the same test using some powdered copper and got a much larger line of copper in the bead. It's very possible that I am not doing this test right but, if it works the way it appears to, it is much easier and more convenient than using ...

Sensor based automatic ore sorting technologies are used in the minerals industries to efficiently remove waste and submarginal grade material from crushed and screened run-of-mine (ROM) ore, producing a coarse (typically >10 mm) upgraded preconcentrate at an early stage in the mineral processing circuit. This avoids additional energy intensive downstream processing of …

ROM (run of mine) gold ore is delivered in large haul trucks (190- and 300- ton capacity) to a series of stockpiles where it is segregated based on ore grade, fuel value, and carbonate content. A loader reclaims ore from the different stockpiles and loads it into smaller haul trucks (85-ton capacity) to create a uniform blend.
