In this mining financial modeling course, we will work through a case study of a real mining valuation for an asset by pulling information from the Feasibility Study, inputting it into Excel, building a forecast, and valuing the asset. Mining financial modeling valuation course objectives
In this study, a magnetiterich ore was comminuted using laboratoryscale SFC and HPGR in opencircuit operations. Both comminution devices were opera.
For a flotation circuit, material balance calculations define an engineering problem where flow parameters between unit operations are partly known. The purpose of a material balancing is to mathematically examine the known flow parameters to solve for the unknown flow parameters. Two main types of material balances are commonly made: design material balance operating plant material .

Calculation of production costs in Excel. The production cost calculation of production is the determination of costs in terms of money per unit of goods, works or services. The calculation includes direct and indirect costs. Direct is the cost of materials, wages of workers, etc. Indirect costs: planned profit, transportation, etc.
These calculations are provided for your information, but SGS cannot guarantee that all data or formulas match the most current standards. Clients trading coal must familiarise themselves with the current standards being used in contracts. *** Net CV calculation refer to ASTM D586512 / .
Mining projects are applying the ageold notion of "check your work" against comminution circuit design, mill power requirement estimates and mill throughput estimates. The best way to test the results of one comminution modelling system is to replicate the calculation in a different modelling system.

Whether you dabble in Excel or use it heavily at your job, there is a function for everyone in this list. 1. CONCATENATE =CONCATENATE is one of the easiest to learn but most powerful formulas when conducting data analysis. Combine text, numbers, dates and more from multiple cells into one.
4. Comminution System To achieve the goal of recovering these concentr ates, the raw ore must be reduced to fine size prior to separation. This process is called ''comminution'' or ''size reduction''. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is ''liberation''.
Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquidtosolid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.
The JKTech DropWeight Test was developed at the Julius Kruttschnitt Mineral Research Centre. The test measures the appearance function of the ore for five size fractions in the range of 13 to 63 mm, at various energy inputs ( to kWh/t).
