What type of mining is the best for the environment?
In situ mining, for example, can be more environmentally friendly than underground mining and is cheaper than many mining methods.
Which type of mining was least damaging to the environment?
Subsurface mines have less permanent damage to the environment, although they still produce many byproducts that are introduced into the environment. Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.
Which type of mining is the least environmentally damaging?
Subsurface mines have less permanent damage to the environment, although they still produce many byproducts that are introduced into the environment. Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.

Which type of mining was worse for the environment?
Surface mining (another name for "strip mining") can severely erode the soil or reduce its fertility; pollute waters or drain underground water reserves; scar or altar the landscape; damage roads, homes, and other structures; and destroy wildlife.
What type of mining has the least impact on the environment?
Subsurface mines have less permanent damage to the environment, although they still produce many byproducts that are introduced into the environment. Placer mining can be less damaging to the environment than surface mines, as the sediment is returned to the water after the minerals have been extracted.
Which type of mining is more environmentally degrading?
Open-pit mining, one of the most common forms, is one of the most damaging. Miners hollow out a section of land, digging down to create a workable area and extract valuable raw materials. This method leaves behind large pits in the earth and can contaminate the groundwater with chemicals used in the mining process.

Which types of mining techniques have the highest impacts on the environment?
Which types of mining techniques have the highest impacts on the environment, and what are those impacts? Surface mining techniques.
What is the ideal combination of chemical properties to support high productivity in a soil?
If it has a relatively high base saturation, its clay particles will hold important plant nutrients such as calcium, magnesium, and potassium. A soil with both high CEC and high base saturation usually supports high productivity.

What are the chemical properties of a soil?
Soil chemical properties discussed below include phosphorus, nitrogen, major cations, trace metals, cation exchange capacity, electrical conductivity, enzymes, organic matter and carbon, base saturation, salinity, sodium adsorption ration, and pH.
What is chemical nature of soil?
Soil chemical properties include concentrations of specific chemicals (e.g. phosphorus, nitrogen, carbon, major cations (calcium, magnesium, sodium, potassium), sulfur, trace metals and elements), pH, cation exchange capacity cation exchange capacity, base saturation, salinity, sodium adsorption ratio, enzymes, and ...
