A parametric cost model for mineral grinding mills more by Ahmad Sayadi ABSTRACT The adequate cost estimation of mill plants plays a crucial role in the success of feasibility studies of mining projects.
A grinding circuit was selected to present the various analyses that can be performed using simulations. The process starts with a stockpile. The ore is transported by a belt conveyor mixed with water and sent to a SAG mill. The pebbles from the SAG mill are sent to a screen and then a pebble crusher. The crusher discharge and the product from

The concept of risk is well established in the mining industry. It is acknowledged when estimates of reserves are expressed as proven or probable when mining and metallurgical recoveries are applied to the ore and when contingencies are added to costs. However it is difficult ot provide a quantitative assessment of risk. The significant sources of risk in a mineral project and how these are .
In feasibility studies and mine planning accurate and effective tools and methods facilitating cost estimation play an important role. Load–Haul–Dump LHD machines are a key loading and haulage equipment in most of the underground metal mines and hard rock tunnels. In this paper a cost estimation model of these vehicles has been presented in the form of single and multivariable functions.
