The process of looking for signs of any mineralisation housed in the nearby rocks is known as mineral exploration. The fundamental idea is to create a geological picture by taking bits and pieces of geological data from several locations and projecting them over a broader area. Exploration proceeds in steps of increasing complexity. Cheaper, less […]

Introduction Drilling is a common activity carried out by mining and petroleum companies. The aim of a drilling campaign varies depending on the result type. Many tools are used during the process including dill rods, casings and water swivels. In this article, we are going to describe each tool and will also share their benefits. […]

The Chuquicamata mine, located in the Atacama Desert of northern Chile, is the second-deepest open-pit mine globally, behind Bingham Canyon in Utah. The terrain has been hollowed down by the extraction of massive copper reserves; the greatest hole at the location is about 1,000 meters (3,300 ft) deep. Although there is evidence of mining in […]

The mining sector is booming due to the market and worldwide demand increase. The use of novel industrial processes and equipment, growth in trained personnel, and growth in managerial skills go hand in hand with the need to increase productivity mining areas. These improvements make the mining industry one of the world’s riskiest and most unstable (Nguembi […]

Employees in the mining, oil, and gas sectors are frequently stationed in isolated and varied areas. These work sites, whether onshore or offshore, are isolated from one another geographically in some way. Operators are required to offer their employees a specific degree of health services while they are at work because of the different demands […]

Hot water acts as a concentrating, transporting, and depositing agent in hydrothermal mineral deposits. Out of all the deposit classes, they are the most numerous. Since pure water is a poor solvent for most ore minerals, hydrothermal deposits are never created from pure water. It would be more accurate to refer to them as products […]

The term “native metal” refers to metals found in pure or in an alloy that is representative of their natural, elemental state. Although a wide variety of metals can be found in native deposits, only few are resistant to oxidation and weathering. Because they are highly reactive when exposed to water, light, and other elements […]

Magmatic sulfides, a significant source of valuable metals like platinum, palladium, and chromium, are formed through a fascinating process within Earth’s fiery depths. The Formation Process Mafic and Ultramafic Magmas: These magma types, rich in iron, magnesium, and sulfur, are the foundation for magmatic sulfide deposits. Early Crystallization: As these magmas cool, minerals like plagioclase, […]

In the econometrics of mineral resources, cut-off grades are threshold values used to determine the economic viability of mining operations. The cut-off grade depends on several parameters, and we primarily distinguish between: The geological cut-of grade The geological cut-off grade is employed to generate frequency distributions of grades to separate mineralised materials from waste and […]

What is a core barrel? The core barrel is an essential part of each coring practice as it collects the core sample in its inner tube and simultaneously its outer tube acts as the BHA. Core barrels are not all the same, but rather differ and have different features and components depending on the coring […]

What is drilling rate index? DRI is a measure of the difficulty or ease of drilling rock, and it was developed at the Norwegian University of Science and Technology in Trondheim, Norway. The DRI value is strongly related to the uniaxial compressive strength and indirect tensile strength. However, when the uniaxial compressive strength and tensile strength […]

Placer deposit are natural concentration of heavy minerals caused by the effect of gravity on moving particles. When heavy, stable minerals are freed from their matrix by weathering processes, they are slowly washed downslope into streams that quickly winnow the lighter matrix. Thus, the heavy minerals become concentrated in stream, beach, and lag (residual) gravels […]

A paper written by: Pascal Amedzrovi, George Agyei, University of Mines and Technology, Tarkwa, Ghana. The most important factor in mine production planning is called cut-off grade. Therefore, it’s accuracy is important as it can seriously impact the net present value (NPV). The Lane’s approach is commonly used to determine the optimal cut-off grade by […]

Location At 170 km southeast of Antofagasta, in the northern Chilean Atacama Desert, sits the copper porphyry deposit known as Escondida. In Spanish, the name Escondida means “hidden.” It comes from the primary orebody, which is concealed by hundreds of meters of overburden and does not outcrop on the surface. Ownership The world’s greatest producer […]
