There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.
The successful development and application of big lump ore dry permanent magnetic separators and high efficiency magnetic drums have enabled the beneficiation of low grade magnetite ore to discard 10% to 30% of tailings in advance, and improve the ore into the grinding grade 2 5% has played a great role in reducing the load in the grinding stage, improving the grinding efficiency, and saving energy and reducing consumption.
plant design should accordingly provide for laydown and workspace for onsite equipment refurbishment and repair. Where possible, equipment manufacturers should be encouraged to stock and provide spare parts close to the mining operation. Good geotechnical information is essential to crushing plant siting and design. Installing a
These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost efficient process designs. Prominer has established strategic relationships with equipment suppliers and commercial laboratories, so that together with advanced technology we deliver the best in gold processing plants.
We know that all ore bodies are unique and whilst our equipment range is extensive and fits most applications, we also design and engineer tailored technology solutions for specific projects. An excellent example of a tailored solution was the development of the HC33 rougher spiral for ArcelorMittals Canadian operations.
The Mercur Gold Project consists of a 2700 tonne per day carbon in leach gold plant. In addition to the process facilities, the project incorporated the following: a) Upgrading and modifying of the existing 11 km of Tooele County road, from State Highway 73 to the project area b) Site earthwork, including construction sediment dams, project area roads and initial mine haul roads c) Preproduction stripping of Mercur Hill Lulu ore body d) Tailings disposal, including embankment, pipeline and recovery systems e) Offices, laboratory, shops, warehouse and security facilities f) Thirteen km water supply line and two 365 m deep water wells. In order to meet both objectives, initial discussions centered on the plot plan and the best location for the facilities, including consideration of the possible need for an oxidation circuit and future expansion requirements. The approximate sizes of the major process areas were developed and cutouts made...

The engineering design schedule for the project required a multiple task approach with design activities underway on several areas at the same time. Communication between each activity was maintained by establishing a project area where all major activities took place. Frequent design development meetings were held so that representatives of all aspects of the project could provide input. The initial flowsheet contained several areas which required further definition. Test work was underway to determine the residence time required for CIL and a study was conducted on the need for pressure oxidation. While this work was going on, specifications for the major process equipment in the comminution circuit were being written. Several alternative layouts were developed for the mills and mill drives. In order to quickly establish the optimum configuration of the mills, a styrofoam model was constructed representing the mills, cyclone feed sump, cyclones, screens and pumps. The requirements...
In addition to the process facilities, the project includes a mine services building which houses a truck shop, mining engineering and geological offices, and a machine shop and maintenance area. Due to the severe space restrictions on the site, all of these facilities were combined into a single unit located so that the mine haul trucks could access the building without entering the process area and so that the process maintenance facility could be near the major process facilities. In addition to the mine services building, a laboratory building, administration building and gatehouse were provided. Other ancillary facilities included water supply facilities, electrical distribution and a tailings pond embankment. The 79 m high tailings pond embankment design required extensive field work, which was accomplished during the fall of 1981. With this work completed, the design and permitting process inherent in a structure of this type was completed over the winter and the fie...
