Operating costs: Per ton basis (e.g., $2.50/ton for mining) Capital costs Cost of Capital Cost of capital is the minimum rate of return that a business must earn before generating value. Before a business can turn a profit, it must at least generate sufficient income to cover the cost of funding its operation.
A breakdown of operating costs for 40 and 50-tonne rear-dump trucks is displayed in Figure 12. Maintenance requirements typically represent the largest fraction of the mine's controllable operating costs, accounting for 30% to 65% of the overall operating cost budget for a typical mining operation.
Mining and processing cost will swing up or down depending upon the production rate. In this example, the production rate is set to 5Mtpa (for the base case), then in creased to 6.5Mtpa,

Only where a group of mines operates in a single district are costs comparable and then only with reservations. In general, cost systems are fairly uniform, yet in studying costs of a number of plants it is noticeable that in some cases there is a tendency to omit certain operations which are proper charges against ore dressing and treatment. These should cover the first stage of .
Feb 16, 2017· Bringing down mining operating costs is not very difficult. However, its sustainability is a different challenge altogether. To bring down costs so that they stay down, companies can try the following: Create processes and methods that improve operations that can sustain for a long time.
Historically, the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite in coarse magnetic separation.
Process Issues can add 10 to 25% to downstream costs through: • Damage to fleet, ore body, mine plan • Inefficient processing • Waste of explosive • Re-work There needs to be sufficient stock of broken ground to: • Deliver preferred material blend to processing plant • Achieve sizing within specification • Ensure effective cycle

Understanding the various costs within the mining industry is integral to recognising why there is such a high project failure rate. In fact, the majority of pre-financial crisis IPOs - between 2005 and 2007 - on AIM were junior mining and oil companies who were taking advantage of the commodity price booms in gold, oil and a range of other minerals and the increased investor appetite they ...
Copper mining is a capital-intensive industry engaged in continuous innovation to reduce operating costs sufficiently to offset declining ore grades and competition from lower-cost sources. Lower operating costs are obtained through increasing economies of scale and labor productivity, which require substitution of capital for labor. In real terms,
May 08, 2020· Mining requires extensive capital expenditures, both for exploration and the initial establishment of mining operations. However, once a mine is operational, its operating costs .
Operating Costs for Miners 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?"
The operating costs of the top four iron ore producers are some of the lowest in the world, and the barriers to entry (upfront capital cost) for suppliers to the iron ore market are high A fully commercial iron ore mine requires heavy capital investment in such infrastructure as rail, and heavy machinery Upfront capital cost for iron ore.
Feb 24, 2015· The cost associated with high-capacity processing of a hard, fine-grained, silica-rich magnetite ore is presented in this paper, with the emphasis on comminution circuit options. The objective is to evaluate several options involving different grinding technologies with respect to energy consumption, operating cost and capital cost.
