A feasibility study on the production of gold at a fictitious mine (Moapa mine) in Elko County, Nevada is to be performed. The mine is capable of producing 325,800 tons of high-grade ore per year for 8 years. The deposit contains 0.12 ounces of gold per ton of high-grade ore and can be acquired at a cost of $10 per ton of ore (cost of mining ore
were made for estimating the costs of small-scale mining and milling methods typically assoc~ated with placer min- ing. The popularity and widespread use of placer mining methods indicated that a cost estimating system for placer mining would be of value to prospectors, miners, investors, and government evaluators.
Mineral reserves are stated within the final design pit based on a US$878/ounce gold price pit shell with a US$1,350 /ounce gold price for revenue. The equivalent cut-off grade was 0.34 g/t Au for all pit phases. The mining cost averaged CAD$ …
The Gold Heap Leach Cost Guide brings all the pertinent costs for gold heap leaching into one convenient reference. The guide provides estimators, engineers, investors and accounting professionals with cost estimating models for mining, heap construction and placing, gold recovery, and reclamation.
- danger of over milling - mills gold to very thin flakes, - stains the gold with iron - not good for batch processing - in non-mining countries, balls difficult to find - high investment costs compared to capacity Ball mill Advantages: - product size can be very fine (e.g. for flotation, < 150µm) - works with very hard material - can be built ...
This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.

Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 60-70% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.
During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine. In times of higher prices, mining low-grade ore will become profitable as the higher price offsets the increased cost of extracting and milling greater volumes.
important factor affecting costs is the size of the mine and pro cessing plant as expressed in terms of tons of ore mined and milled per day of operation. 6.3.2.1 Mine Size or Production Rate After discovery of an are body, the mining and milling rate for the proposed mine project should be chosen such that the
