Green mining processes refer to environmentally-friendly practices in the mining industry that aim to reduce the impact of mining operations on the environment. This can include using renewable energy sources, recycling materials, minimizing water usage, and reducing greenhouse gas emissions. The goal is to promote sustainability and minimize the negative effects of mining on ecosystems and surrounding communities.

Most metallic ores are produced by which two types of processes?
Most metallic ores are produced through mining and extraction processes. Mining involves the physical extraction of ore from the earth, while extraction processes such as smelting, leaching, or electrolysis are used to extract the desired metal from the ore.
How can mining harm the environment?
Mining can harm the environment through deforestation, habitat destruction, soil erosion, water pollution, and air pollution. Chemicals used in mining processes can contaminate soil and water, threatening the health of both humans and wildlife. Additionally, mining can disrupt ecosystems and lead to the loss of biodiversity.
What is the process of removing metals etc. from the Earth?
The process of removing metals from the Earth involves mining, which typically starts with exploration to identify mineral deposits. Once a deposit is found, the ore is extracted through mining techniques such as surface mining or underground mining. The extracted ore is then processed to separate and extract the desired metal using methods such as crushing, grinding, and chemical processes.
Why are placer mining hydraulic mining and hard-rock mining different?
Placer mining involves extracting minerals from loose material such as gravel or sand, usually done by panning or sluicing. Hydraulic mining uses high-pressure water jets to dislodge material and extract minerals, often causing environmental damage. Hard-rock mining involves extracting minerals from solid rock formations, requiring drilling and blasting techniques. Each method has distinct processes and impacts on the environment.
How is ore extracted from the ground?
The general term we apply to ore extraction from the earth is mining, and mining technology or mining engineering are the disciplines under which mining is practiced. Need a link? You'll find one below to the Wikipedia post on mining. If your question is applied to the mechanics of mining, we have to locate and map deposits of mineral ores. Then sample and test them for concentration ("richness"). Then either dig a shaft or start removal of overburden to form a pit. We can drill to set charges, blast, and then send in men and equipment to remove the material and get it out to a place from which it can be routed to processing, either on site or at a remote location.
Why does mining offend people?
They do not understand how much of what they use every day came from mining. They also have little understanding of mining processes.
What has the author Larry E Green written?
Larry E. Green has written: 'Comparative shortwall and room-and-pillar mining costs' -- subject(s): Pillaring (Mining), Mining engineering
What is a mill in mining?
The machinery that crushes or processes the material that has been mined.
What is the processes that bauxite goes through from mining until it changed into alumina?

How is plutonium used in gold mining?
Plutonium is not commonly used in gold mining. Plutonium is a highly radioactive element that is used in nuclear reactors and nuclear weapons, but it is not typically associated with gold mining processes.
What are jobs duties and skills of mining engineers?
The jobs duties and skills of mining engineers are quite diverse. This includes overseeing and outlining mining processes and projects. They also serve as consultants who give guidelines on various issues related to mining.
Most metallic ores are produced by which two types of processes?
Most metallic ores are produced through mining and extraction processes. Mining involves the physical extraction of ore from the earth, while extraction processes such as smelting, leaching, or electrolysis are used to extract the desired metal from the ore.
When are rocks and land moved?
This happens during road building, mining and by natural processes such as landslides and earthquakes.
What is the importance of thermodynamics in the field of mining engineering?
Thermodynamics plays a crucial role in mining engineering by influencing the processes of extraction and processing of minerals. It helps engineers understand energy transformations and the efficiency of operations, such as ore heating and smelting. Additionally, thermodynamic principles are essential for managing heat and energy consumption in mining activities, thereby reducing costs and environmental impacts. Overall, a solid grasp of thermodynamics enhances the design and optimization of mining processes.
What are the enviromental impacts of mining gemstones?
Mining natural resource produces environmental impacts. Responsible mining operations consider these impacts, and address their potential damage as part of their mining operations. Impacts might include "... erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes." This list according to Wikipedia, below.
