Opening a new mine or expanding an existing operation can be a challenging and daunting task. Aside from assessing and evaluating social-environmental concerns and designing the mining and material movement approach, the first question often asked is, "how much will it cost us to mine?" This may need to be determined even before you decide that there is a potential project.

Estimating the cost per ton blasted is a crucial aspect of financial planning and operational management for mining companies. However, it can be complex when miners encounter variations in ore quality and mineralogy, which …

In this paper, cost uncertainty is considered as cost of under production, and cost of over production. The cost uncertainty model is developed using the real option techniques. The...

By calculating the metal value and then deducting the estimated mining costs, ... (0.145 / 0.029 =) 5 grams per tonne. Conversely, when a mining company reports a drill result of 10 grams per tonne, you now know that this equals (10 x 0.029 …

The capital cost per tonne of annual production is $1. Option two costs $0.5m but $3m to install, and it will process 1mt/y. The total capital cost per annual tonne is $3.5.

For open pit mining the costs are $0.40/ton ore and a stripping cost of $0.50/ton of waste. SR = (3.00 –0.40)/0.50 = 5.2 tons of waste/ ton of ore i.e. while the stripping ratio is less than 5.2 it is most economical to mine the deposit by …

This despite a number of articles, such as by PWC, and two excellent notes, one a kitco article dated 4 February 2015 with the title as "The Real Cost of Mining …

Where T = tons of ore per hour. and Q = tons of added water per hour or T = tons of ore (for batch determinations) and Q = tons of added water. In both cases Dx and D2 are dilutions (tons of water per ton of ore) before and after addition of water.

Example for Calculating the Potential Mineral Deposit Value. In a company's news release in which their drill are announced, you can find the following information: Average Grade: the concentration of a mineral in the ore body (in …

Example for Calculating the Potential Mineral Deposit Value. In a company's news release in which their drill are announced, you can find the following information: Average Grade: the concentration of a mineral in the ore body (in % or g/t) – 2% copper and 1.5 grams per tonne gold

With the increase in the cost of mining general and especially the cost of labour it is now standard practice to beneficiate the ... assumed that pelletising UG-2 ore costs $15 per tonne of ore.
