Introduction Mining pollution refers to the environmental contamination and degradation caused by the extraction and processing of minerals. One major environmental issue brought on by operations involving the extraction and processing of minerals is mining contamination (comunicación, 2023). Sustainable development objectives call for a considerable reduction in atmospheric pollution, and mining companies are no exception to […]

Introduction Crushing represents a fundamental and often energy-intensive stage within mineral processing and aggregate production circuits (Gawenda & Saramak, 2022). These operations, involving the size reduction of rock, ore, or other raw materials, are critical for preparing materials for subsequent processing steps like screening or grinding, or for producing final aggregate products meeting specific size […]

Indian miner NMDC  is exploring coking coal assets, key ingredient used for making iron ore and steel, in Indonesia and Australia, Chairman Amitava Mukherjee said on Thursday. India, the world’s second-largest producer of crude steel, meets 85% of its coking coal requirements through imports. Australia accounts for more than half of the country’s coking coal imports. […]

Introduction Electronic detonators are advanced initiation devices used to trigger explosives, typically in mining and civil engineering, that utilize electronic circuits and microchips to control the timing and sequence of detonations. Unlike traditional electric and non-electric detonators, they offer precise timing control, enhanced safety, and reduced sensitivity to stray electrical currents, according to the Federal Register […]

Introduction Blasting, the primary method for rock breakage in mining and construction, relies fundamentally on initiation systems to trigger explosive charges. These systems have evolved significantly over time, progressing from rudimentary methods like safety fuses and blasting caps to more sophisticated electric and non-electric detonators. Electric detonators utilize an electric current passed through a resistance […]

What is rock drillability? Drillability of rock refers to the ability of rock to resist pressure and crushing during drilling, it also indicates the efficiency of footage, and it is also an index of rock solidity that indicates the difficulty of drilling blastholes (Alicia, 2023). Drillability, in other words, may be measured by the drilling speed […]

The 3-month nickel contract on the […]

In our modern lives, minerals are the silent architects that shape our daily experiences, yet we rarely acknowledge their presence. These geological treasures extracted from the Earth’s crust contribute to countless products, technologies, and structures that have become integral to our existence. This article provides the top five minerals that play crucial roles in our […]

Introduction A mining operation was experiencing significant disruptions after its recent transition to an autonomous haulage system (AHS). Frequent stoppages due to various factors were hindering productivity and negatively impacting overall operations. To address these issues, the company implemented Haul Road Explorer (HRE) to help optimise its autonomous haulage systems and obtain the highest value […]

According to a Research report, the global detonator market is predicted to grow by 733.6 million by 2026 which is slightly less than what was predicted in the year 2020. But because of the pandemic, the entire global economy has come to a standstill but every industrial explosives company in India is ensuring to manufacture […]

“I’ve often been asked what my day is like as a geologist.  I usually ramble on and on about what I do, but I’ve never put it down in writing so students or anyone else interested could gain an understanding of my job.  So, I decided to write this blog to describe what my job […]

Introduction A vital component of the global economy, mining supplies the basic materials that power our contemporary civilization. But conventional methods can have disastrous effects on the environment, causing habitat destruction, water source depletion, and climate change. A novel strategy that is gaining popularity to allay these worries is green mining. Definition Green mining is […]

Dilution occurs when waste material is mixed in with the ore during the mining phase and fed to the processing plant. The discrimination between ore and sub-economic dilution material is the site – and process specific cut-off grade (Dilution – SIX-S GmbH, n.d.). What are the types of dilution? Internal dilution and external dilution are […]

Introduction Gossan is intensely oxidized, weathered or decomposed rock, usually the upper and exposed part of an ore deposit or mineral vein. In the 19th and 20th centuries, gossans were important guides to buried ore deposits used by prospectors in their quest for metal ores. An experienced prospector could read the clues in the structure […]
