1.1.3 active mining once a mining company has constructed access roads and prepared staging areas that would house project personnel and equipment, mining may commence. all types of active mining share a common aspect: the extraction and concentration (or beneficiation) of a metal from the earth. proposed mining projects
total capital costs of the expansion project are estimated at $300 million, including $130 million for capital equipment and the balance in pre‐production stripping over the period of 2009 through 2013. approximately $50 million of mobile mining equipment will be ordered in 2007 to permit waste stripping to commence in 2009.
grade ores and continually reduce the costs of production. economies of scale have been real-ized in all phases of copper production. both ma-chine and human productivity have increased dramatically. this chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or
end mills are made out of either cobalt steel alloys (known as high speed steel, or hss), or from tungsten carbide in a cobalt lattice (shortened to 'carbide'). high speed steel (hss): provides good wear resistance and costs less than cobalt or carbide end mills. hss is used for general purpose milling of both ferrous and non-ferrous materials.
the planner milling machine is mostly used for facing operations in mass production. these machines are similar to the bed type mill machine, except it can be mounted with various cutters and spindle heads to the machine. these cutters in the machines can perform the facing operations simultaneously which is a great function. special milling machine:

two distinct set of factors drive mining cash costs: the first set of factors relates to the actual costs of inputs: skilled labor, mining materials, equipment, reagents, structural steel, and everything else that goes into running a mine. the second set of factors relate to the price of the underlying metal of the mine.
industry standard reference of capital costs and hourly operating costs for over 3,000 pieces of mine and mill equipment from $500 slusher buckets to $50,000,000 walking draglines. the calculator allows you to adjust the parameters for calculating hourly costs, such as repair labor, diesel fuel, gasoline, natural gas, electricity and lubricants.
waste dumpsites. the ore is re ned at the mill, while the stockpiles store supplementary material for ensuring that the mill receives the correct mixing of ore grades to meet market demands. the long-term mine plan optimizes the timing of bench development, such that market demand is met and the value of the mine is maximized.
mining cost service continues to be a useful reference on a wide range of topics for early stage mine planning through to ‘fill the gaps’ on more detailed studies. mining cost service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.
