The Application and Benefits of GPS-Based Bucket Positioning and Production Reporting on Draglines.

CIM Edmonton 2004
Carl Hendricks,
Abstract This paper describes the design, development and user benefits of Aquila's dragline guidance system, which incorporates 3D GPS-based bucket positioning and comprehensive production monitoring. Aquila prototyped its first GPS guidance systems for drills in 1993 at the Gregg River Mine and since then along with its parent company, Caterpillar, have delivered hundreds of GPS guidance systems for drills, dozers, loading and support equipment of almost every major type seen in mining. A notable exception however, has been dragline's, which despite their greater reliance on careful design and survey support to ensure optimal productivity had previously not attracted a GPS solution from the suppliers of traditional dragline production monitoring systems. Combining precise, real-time bucket positions with the detailed production cycle data and load weights - being provided through a partnership with Drives and Controls Services (DCS), has resulted in a more meaningful production tool that allows complex designs to be precisely communicated to the operators and the as-built results to be more accurately controlled.

Summary: Mining process simulation modeling will be discussed. A particular emphasis will be on the oil sands. The concept of a ‘Model for Life’ will be presented. The details in the model are consistent with the phase of the project. The first model for a project would be fairly high level/macro. As more detail and accuracy are required in estimates of capital and production, the detail in the model is increased. When the project in operating, more detail is added to reflect the operating details....

Summary: Removal of carbonate gangue and pre-concentration of sulfide minerals is necessary prior to acid pressure leaching when a refractory gold-bearing sulfide ore contains a significant amount of carbonate minerals. This is usually achieved by direct flotation of the gold and sulfide minerals into a bulk flotation concentrate. However, if the flotation recoveries of gold and sulfide are unsatisfactory, reverse flotation of the carbonate minerals is a possible alternative. In this study, calcite...

Summary: The energy required to fragment a rock is proportional to the increase in the fracture surface area and hence is proportional to the rock’s surface area. In comminution, the slope of the linear relationship between size reduction ratio and specific energy is usually defined as grindability. Another definition of grindability based on newly created specific surface area and specific energy is introduced. The two definitions for grindability reflect the grindability properties of rocks and...

Summary: We document the occurrence, mineralogy and firing properties of magnesite from hydrothermal deposits in the upper Cretaceous ophiolites of Eastern Iran.
These deposits occur as thin veins of nearly pure cryptocrystalline magnesite with only trace amounts of quartz, calcite, and dolomite. Ratios of CaO/SiO2 in the bulk ore are variable. The composition of dead-burned magnesite from these deposits, calcined at different temperatures and durations, is predictable from phase equilibria. ...
