OPERATIONS MODELING AND ANALYSIS OF OPEN PIT

2013-5-21  Open pit copper mining plants usually comprise two major components, the open pit mining operation and the copper ore enrichment plant. An open pit copper mine is an excavation or graze made into the sur-face of the ground for the purpose of extracting ore. A series of data obtained by a transportation control system with GPS (Global Positioning System) technology is utilized to perform the simulation. Opera-tions in the mine are based on a mining plan and must be optimized because the transportation costs are expensive. In this paper, procedures are proposed to obtain an optimized number of trucks and to estimate the maximum mining capacity at an open copper pit. Then, the creation of a truck dispatching control ta-ble for meeting the maximum mining

Introduction to Spectroscopy: Analysis of Copper Ore

2008-7-8  In this experiment, your group will analyze solutions made from copper ore extracted from both sites found by the mining company. In order to leach the copper from the ore and obtain a solution that can be analyzed, the solid ore sample was first dissolved in sulfuric acid and then filtered to remove sediments. Your group will analyze the resulting solutions from sites A and B to determine the concentration of copper at each site and determine if they are economically feasible to mine.
