A nonlinear cost relationship often used in estimating the cost of a new industrial processing plant from the known cost of an existing facility of a different size is known as the exponential rule. Let y n be the known cost of an existing facility with capacity Q n, and y be the estimated cost of the new facility which has a capacity Q.
RPA's capital cost estimate included all aspects of project development, including mining, mineral concentration, and hydrometallurgical processing, but …
The Cost Estimating Series: Capital Cost Estimate Classes. Whether building new process lines or renovating existing lines, capital and operating and maintenance (O&M) cost estimates are important for project planning and implementation. The following will provide an overview of the classes of capital cost estimates.
This Bureau of Mines publication presents a method for estimating capital and operating costs associated with the exploration, mining, and processing of placer deposits. To ensure represent- ative cost estimates, operational parameters for placering equipment and basic principles of placer mining techniques are detailed. - - I M~ning engineer.

mill capacities. These costs were estimated from inhouse historical data for a variety of plant capacities, as illustrated below. These estimates were based on a hypothetical mine with the key assumptions, as outlined below in Table 3.

This is a question that comes up quite often in capital cost estimating. So, I thought I would share my point of view and experience on this subject. Generally speaking, I would say that the Owner's costs are all the costs required to bring a project to a commercially operable status, less the cost of the EPC contract.
expressed as a percentage of the capital cost of the project. • Scoping study 0.1 to 0.3 per cent •Prefeasibility study 0.2 to 0.8 per cent • Full feasibility study 0.5 to 1.5 per cent. Accuracy of cost estimates The accuracy of capital and operating cost estimates increases as …

C = F * Sum (C_e) C is the total capital cost, F is the installation factor also known as Lang factor, and C_e is the cost of major equipment. Lang factor is 3.1 for solid processing plant and 4.74 for fluids processing plant. Better estimate can be made when the different factors are used for corresponding equipment.
Typically, in a phase-gate project system, scope definition and capital cost estimating activities flow from framing a business opportunity through to a capital investment decision and eventual project completion in a more-or-less steady, short-term (e.g., several years) project life-cycle process.
Introduction. The cost-to-capacity method can be a very useful tool when developing elements of the cost approach in many valuations. It is a order-of-magnitude cost estimation tool that uses historical costs and capacity in order to develop current cost estimates for an entire facility or a particular piece of machinery or equipment [1].
The increased focus will apply specifically to copper and steel-making products (zinc and iron ore), with the production of the precious metals as a valuable cost-credit byproduct.

Remaining initial capital cost, including contingency, is US$0.71 billion, with subsequent expansions at Kansoko, Kakula West, and other mining areas, as well as the smelter, to be fundedbycash flows from the Kakula Mine. Average total cash costs of US$1.07/lb. copper during the first 10 years, including sulphuric acid credits.

Methods For Estimating Capital Investment 3. Percentage of Delivered-Equipment Cost. All items in the direct and indirect cost are evaluated as a percentage of the delivered-equipment cost. (definitive estimate in certain cases, ±10% ) See Table 7-8, p. 194 in TBW&S 4. Estimation based on "Lang" factors . Named after Lang (1947).
a capital cost of approximately $200M. The scope of this current estimate was restricted to the Kundip resource and considered just two metallurgical domains –the low copper oxide and the high copper sulphide. This greatly simplifies the process design. In addition, as …
In this research we employed and compared two methods to estimate future copper demand: A top-down, regression-based, and a bottom-up, stock-dynamics-based, method. The copper demand estimation for the year 2100 depended strongly on the method used, in particular for extreme scenarios and a long prediction time.
The roasting cost works out at approximately $1.22 per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941- 1942 was 32 cents per ton milled or $1.25 per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.
Effective costs of Copper Processing As each tonne of ore produces 0.0051 t of copper in concentrates, with a free market value of £ 5.00, so total production costs of copper in concentrates : However, if the ore contains appreciable by-products, the effective production costs are reduced. Assuming the concentrate contains 25 gpt of gold and ...
