Apr 05, 2017 Expressed in another way, the sorting cost per ton of run-of-mine ore is 1.956.51 or 0.30. The cost of mining 1 ton of run-of-mine. ore is 2.34. The cost of transporting ore from the mine to the mill on contract is 1 per ton. The milling cost of run-of-mine ore is taken as 2.85 and the cost of milling the sorted product is 3.22 per ton.
Bulk mining - Any large-scale, mechanized method of mining involving many thousands of tonnes of ore being brought to surface per day. Bulk sample - A large sample of mineralized rock, frequently hundreds of tonnes, selected in such a manner as to be representative of the potential orebody being sampled.
For example, a 6.0 meter subgrade on a 30 percent slope with a 1.51 fill slope and 0.51 cut slope with a one foot ditch and a 20 percent shrinkage factor would be approximately 2100 bank cubic meters per km for a balanced section.

Oct 30, 2018 That means mining 1 cubic meter of ore would require mining 3 cubic meters of overburden. The stripping ratio of a deposit may be used, in part, to gauge how profitable it may be.
The sailing time is dependent upon the distance between the borrow source and the reclamation area. If the source is close to the reclamation area, many trips per day are possible. In such a situation, as much as 4.0 million m 3 per month of production is possible with the trailer suction hopper dredger. Figure 6.6 shows a dredging operation ...
These rope shovels weigh a staggering 1,390 tonnes, the equivalent of 630 light trucks, and can transport up to 127,000 tonnes per day. Quellaveco will also utilize the first Cat 6060 Hydraulic Mining Shovel in Peru, which features a 67-tonne bucket payload. Innovation is a central tenet of Anglo Americans work.
barrel for crude bitumen. The employment of huge mining machines and process plants in oil sands mines make capital cost a major part ofthe total cost.

If you mine 20 hours per day and 30 days a month, it computes to 240,000 cubic yards a month. If the average grade of the ground is 10 per yard, then your gross revenue is 2.4 million per month. The operating cost should be in the vicinity of 5 per yard. Two to three men per shift can operate a dredge. In one summer, a dredge can be paid off.
