Mineral processing plants require a storage buffer to bridge differences in production rates betweenmining and processing. Where coarse ores are processed, such as coal or hard rock, this buffer maybe an ore stockpile or silo. For wet-mining processes, e.g. dredging or hydraulic mining, or where f ine ores are slurried close tothe mining face, a surge-bin is used to contain the plant feed and smooth out the variations in miningrates. These bins have gradually evolved from simple storage vessels to units that are now frequentlypart of the mineral separation process itself, such as providing a desliming function to removedeleterious ultrafine gangue. This feed conditioning is often essential to achieve the levels of plantperformance required in times of declining ore grades and or where inherent ore characteristicsmake separations harder to achieve. To achieve these dual roles requires careful consideration of bin design factors such as geometryand lining selection and increased use […]

Trenchless Technology Trenchless Construction Drilling Pipe Trenchless technology represents a kind of subsurface construction methodology that necessitates minimal or no continuous trenching. Constituting a swiftly expanding segment of the construction and civil engineering domain, it can be delineated as “a set of techniques, materials, and machinery that can be employed for installing fresh or substitute underground infrastructure, or for revamping the prevailing ones, with negligible interruption to surface traffic, commerce, and other pursuits.” Trenchless Technology Trenchless Construction Drilling Pipe Trenchless construction encompasses various methods such as tunneling, microtunneling (MTM), horizontal directional drilling (HDD), also referred to as directional boring, pipe ramming (PR), pipe jacking (PJ), moling, horizontal auger boring (HAB), and other underground pipeline and cable installation techniques that minimize excavation. Large-scale subsurface projects like those employing a tunnel boring machine (TBM) or drilling and blasting methods are extensions of this concept on a grander scale. The distinction between trenchless […]
Vacuum Ceramic Filter Characteristics Parameters The most important operating parameters of disc filters are the height of the slurry tank, agitation and the intensity and rotation speed of the disc as these will determine the cake formation and drying times. It is important to continuously agitate the slurry in order to prevent sedimentation of the solids. Excessively high agitation intensity may affect cake formation or change the particle size distribution of the product. One of the most commonly used agitators for filtration using vacuum disc filters is an oscillating cradle-type agitator located in the bottom of the basin, which requires fairly high rotation speeds to form homogeneous slurry. For processing rapidly settling high concentration slurries, bottom-feed rotary disc filters are usually used. Stage 1: Filtration During the filtration stage, the low vacuum applied to the filter removes the filtrate from the internal passageways of the discs. The slight pressure difference […]
Vacuum Filter Ceramic Filter A vacuum ceramic filter is designed to facilitate the separation of liquids from solids, primarily for the dewatering of ore concentrates. This device comprises various components such as a rotator, slurry tank, ceramic filter plate, distributor, discharge scraper, cleaning device, frame, agitating device, pipe system, vacuum system, automatic acid dosing system, automatic lubricating system, valve, and discharge chute. While its operation and construction principles bear similarities to a conventional disc filter, the key difference lies in the use of a finely porous ceramic disc as the filter medium. This ceramic disc material exhibits inert properties, boasts a long operational lifespan, and demonstrates resistance to a wide range of chemicals. To optimize performance, it is crucial to consider the various factors that impact the overall efficiency of the separation process. Some of the key variables influencing the performance of a vacuum ceramic filter include solid concentration, the […]
Mineral Processing, Mining Process Mining engineers employed at an established mine may serve various roles, including operations enhancement, mineral prospecting, and optimizing mine capitalization, deciding where to allocate additional equipment and staff within the mine. These engineers might also oversee and manage operations or engage in equipment and mineral sales. Apart from their engineering and operational duties, they could function as managers of environmental, health, and safety aspects or as design engineers. Mining practices depend on the mineralogy, geology, and location of the resources being extracted. Factors such as mineral hardness, stratification, and accessibility influence the chosen extraction method. Mining is broadly categorized into surface and underground operations, and sometimes both methods are used simultaneously in the same mining site. The approach to mineral extraction varies based on the chosen mining method. Surface Mining Surface mining, mineral accounts for 90% of global mineral production by tonnage. Also known as open […]
Mining Operation and Process: Focus on Copper Mines Mining, especially copper mining, is a complex operation that involves various stages from exploration to production. The process of extracting copper from the earth requires meticulous planning, precision, and a range of specialized equipment. Let’s delve into the specifics of copper mining operations and processes. Exploration Phase The initial step in any mining operation is the exploration phase. Geological surveys are conducted to identify potential copper deposits. This involves studying rock formations, soil samples, and other geological indicators to pinpoint areas rich in copper ore. Modern exploration techniques often employ advanced geophysical surveys, such as magnetic, gravity, and electromagnetic methods, to detect subsurface anomalies that might indicate mineral deposits. Mining Methods Once a copper deposit is located, mining engineers must determine the most efficient and safe method to extract the ore. Copper mines can be open pit or underground, depending on the […]
Mineral Exploration Mineral exploration, a more rigorous and professional endeavor compared to mineral prospecting, involves searching for commercially viable mineral deposits suitable for mining. This process goes beyond mere prospecting, employing intensive, organized, and involved techniques often utilizing professional exploration services. The initial phase of mining commences with the discovery and assessment of a mineral deposit. During this early exploration stage, geologists and surveyors play a pivotal role in conducting the preliminary study to assess the feasibility of a potential mining operation. Various prospecting methods are employed to explore and estimate mineral reserves, determining not only the type and form of mining required but also the profitability of the venture. Ref: geology, geological exploration, geologist Mineral Discovery Once a mineral deposit of sufficient economic quality for mining is discovered, mining engineers are tasked with developing an efficient and effective mining plan. Mineral discoveries can stem from examining mineral maps, academic […]
What is Mining Engineering? Mining, within the realm of engineering, involves the extraction of minerals from beneath the surface, within open pits, above, or directly on the ground. This discipline intersects with numerous others, encompassing mineral processing, exploration, excavation, geology, metallurgy, geotechnical engineering, and surveying. A mining engineer oversees various stages of mining operations, encompassing the exploration and discovery of mineral resources, conducting feasibility studies, mine design, planning, production, operations, and ultimately mine closure. During the mineral extraction process, a certain amount of waste and uneconomic material is generated, serving as the primary source of pollution in mining areas. By their inherent nature, mining activities disrupt the natural environment surrounding the mineral deposits. Therefore, mining engineers must prioritize not only the production and processing of mineral resources but also the mitigation of environmental damage both during and after mining activities, addressing the changes that occur in the mining area. Such […]
