The ore of a gold mine in the Mountain Province contains, on the average, 0.5 gram of gold per ton. One method of processing costs P1,650 per ton and recovers 93% of the gold, while another method costs only P1,500 per ton and recovers 81% of the gold. If gold can be sold at P8,500 per gram, which method is better and by how much?

In the new gold mining area in Davao, the ore contains, on average 1 ounce of gold per ton. One method of processing "A" costs P1,500/ton and recovers 90% of the gold. Another method B costs only P1,200/ton and recovers 80% of the gold.
Operating costs for Phase 2 are estimated at $10.27 per tonne of ore processed, as summarized below. Cash costs are estimated at $806/oz with AISC estimated at $858/oz of gold sold.
The grade of mined, raw gold ore is measured in grams of gold per tonne of ore. High-grade gold ore contains more gold per tonne; this means that more gold is obtained from every tonne mined. This greatly increases the profitability of a mine. Indeed, the high cost of processing extremely low-grade gold ore may actually make mining financially ...
The following parameters are applicable to the potential open pit exploitation of this gold deposit: - Rock contained in each block: 2, 000, 000 tonnes - Mining cost (ore & waste): $4 per tonne for level 1 increasing by $1/ t each level - Processing cost: S6 per tonne of ore - Mill recovery: 80% - Gold price: $18 per gram a.

It is important to note that the additional processing steps required for treating refractory ores generate additional costs compared with conventional plants; however, the reserve grade for these ores is on average 86 percent higher than those of nonrefractory-type deposits (2.25 grams per metric ton on average, versus 1.21 grams …
The cutoff grade is the grade at which the cost of mining and processing the ore is equal to the desired selling price of the commodity extracted from the ore. ... a plant recovery of 92%, a mining and processing cost of $6.80/ton and a selling price of $0.74/lb. Be careful with the units! Solving the equation for grade, we have: G = (M&P cost ...
A gold processor has 2 sources of gold ore, source A and source B. In order to keep his plant running, at least 3 tons of ore must be processed each day. Ore from source A costs $20 per ton to process and ore from source B costs $10 per ton to process. Costs must be kept to less than $80 per day.
Operational costs per metric ton of processed ore are higher on average. Operational costs vary depending on the mining method and is notably 50 percent …
The processing fee floor value was determined from a supply cost analysis at a gold price of US$300 per ounce and a grade of 10 grams per tonne. It was determined that a charge of US$54 per tonne of ore is required to obtain a 25% rate of return on the project (at a gold price of US$300 per ounce).
This could be made up of either the processing of 1 mtpa of ore and 9 mtpa of waste or 4 mtpa of ore and 6 mtpa of waste. As the cost to mine waste is less than the mining and treatment costs for the ore, the cost per tonne are likely to be higher for the latter case, if all other factors are equal. Variation in underground operating costs will ...
Operating costs for Phase 2 are estimated at $10.27 per tonne of ore processed, as summarized below. Cash costs are estimated at $806/oz with AISC estimated at …
The leaching costs are dependent on reagent consumption and length of period of treatment, and thus can vary appreciably. A reasonable leaching cost reportedly is $0.50 per ton of ore. Operation of the carbon desorption unit costs about $0.02 per ton of ore, assuming that the ore contains 0.05 ounce of recoverable gold per ton and that the ...
From the viewpoint of mineral economics, the ultimate and significant production cost is that per unit of metal produced rather than the cost per ton of ore treated. This viewpoint is natural to processors of ores whose final product is refined or unrefined metal, whether they be companies engaged solely in smelting, or integrated …
