Mineral Processing. The ore types at Duddar consist of massive and disseminated structures and it appears that a reasonable quantity of the ore types contain the economic minerals in fine associations with each other and the marcasite/ pyrite. A feature of the ores is the in situ interactions between the marcasite/pyrite and both the galena and sphalerite.
Mineral Processing. The Saindak processing circuit is conventional and employs a three stage crushing circuit, two stages of milling followed by a flotation circuit which includes a regrinding mill.
Mineral Processing. Minerals Processing capabilities are at the entry point of the metallurgical value chain, and focus on exploiting the physical properties of minerals for upgrade or concentration purposes. In this regard, Mintek plays a pivotal role within the mining value chain as its spectrum of service offerings is diverse and includes metallurgical optimisation solutions, assessing technology innovation, close interaction with mining sectors and technology suppliers as well as preparing and pre-concentrating material for downstream operations. Mintek is at the forefront off mining challenges thereby offering relevant solutions that support exploration, growth and sustainability. The goal in mineral processing is to produce maximum value from a given raw material and to derive value from unexplored and sterile resources. In this space, Mintek provides metallurgical solutions for the recovery of minerals from a large variety of ores. This is achieved by means of desktop, laboratory and pilot plant studies to develop the most suitable plant configuration for existing operations, new projects or ore types. With respect to mineral processing, Mintek’s research goals are aimed at providing solutions on pre-concentration of commodities that are of greatest economic and strategic importance to the country, notably Precious, Ferrous, Energy, Industrial, Base metals and Rare earth elements. Although the particular research questions that Mintek works on varies across the different commodities, the over- arching and cross-cutting research themes has been: accessing and processing of low-grade and complex ore bodies; development of water-efficient and water-less processing technologies; development of energy-efficient technologies and advancing sensor-based rock sorting technologies. Mintek’s services usually result in the commercialisation of new or improved technologies within the mining and metallurgical industry. It is thus a vital partner in ensuring the sustainability of the SA mining industry through leading technology innovation in mineral liberation and separation and enabling optimal solutions for the beneficiation of strategic and complex minerals.
Mineral Processing. Minerals Processing contributes to the mining sector by conducting research, development and innovation in physical mineral upgrading processes and technology. It focuses on exploiting the physical properties of minerals for upgrade or concentration purposes. The overall aim in mineral processing is maximise the value that can be derived from any raw material and any unexplored or sterile resource. This is achieved by means of laboratory and pilot plant studies to develop the most suitable plant configuration for existing operations, new projects or ore types. MPD’s research goals are aimed at providing solutions on pre-concentration of commodities that are of greatest economic and strategic importance to South Africa, notably Precious, Ferrous, Energy, Industrial, Base metals and Rare earth elements. Objective Equipment improvement and development Objective statement The objective of the programme will be to develop and provide locally manufactured products and equipment to the mining industry to enhance the operational performance of mineral separation process plants Baseline The programme did not exist in the past. This is a new programme that will be started in financial year 2021. Technology is at TRL 4 (Bottom driven cell prototype has been developed).
Mineral Processing. This section shall include a plan for the processing and marketing of Minerals from the Property, whether such processing is to occur on the Property or elsewhere. It shall include: a description of all existing metallurgical test work, design criteria, a description and flowchart for proposed mineral processing procedure and tailings management, process capital and operating costs and production forecasts. It should clearly outline how the bulk/metallurgical sample was collected and should leave no questions regarding the representative nature of the sample. A manpower estimate in the form of an organization chart and work schedules should also be included. As is outlined in the Mining section of this schedule, capital and operating costs shall be based on detailed estimates and an appropriate amount of site investigation work (topographic surveys, foundations testing, permafrost studies, overburden testing).
Mineral Processing. This section shall include a preliminary plan for the processing and marketing of Minerals from the proposed or actual Production Lease Area, whether such processing is to occur on the proposed Production Lease Area or elsewhere. It shall include: a description of preliminary metallurgical test work, assumed design criteria, a description and flowchart for proposed mineral processing procedure and tailings management, process capital and operating costs, and production forecasts. A manpower estimate in the form of an organization chart and work schedules should also be included, consistent with the understanding of the project at the time of preparation of the Prefeasibility Study. Costs shall be based on order of magnitude contractor estimates and internal company files.
