4 types of mining that causes environmental damages

If mining is not regulated, it can release harmful substances into the air, water and soil. Companies work hard to reduce these harmful effects. Here are the kinds of mining that cause environmental damages.

Open pit mining

It is the most common type of mining. It causes damage to the environment as a large amount of ore must be removed to get the small amount of mineral that is available. It can expose rocks that have been unexposed for many years, and when these are crushed, they may release radioactive elements, metallic dust, etc. into the air.

Underground mining

This method of mining involves huge movements of waste rock and vegetation. It can release toxic compounds into the water and air. Water becomes a contaminant and so pollute the surrounding region. In underground mining, hydraulic pumps are used which can remove the important topsoil that contains seed banks. So, it is difficult for vegetation to grow.

Heap leaching

With this method of mining, toxic heap leaching fluids are released into the environment. It can affect the health of the people and the surrounding ecosystem as well.

Brine mining

This involves extracting and evaporating the brine solutions to get rid of the harmful elements. In doing so, these elements are released into the air. The drilling operations and transportation of brine solutions can affect the ecosystems.

During mining, precautions must be taken so that no harm is caused to the environment. Today’s companies use various methods of controlling or eliminating the release of harmful substances into the air, water or land. We should protect our environment by all means.

Top 5 factors affecting exploration of mineral resources

The demand for mineral resources is increasing. So, many companies are getting engaged in the exploration activities to get more minerals to meet the demand. Here are the major factors that affect the exploration of mineral resources.

Richness of the ore

The amount of minerals available determines whether it can be explored or not. It is more economical to work with higher grade ores. These ores are easy and cheap to smelt. High-value minerals like uranium, gold, copper, etc. can be mined at a high cost as their demand is high and so can be sold at higher prices.

Size of deposit

Mining needs a large amount of expensive equipment. The deposit must be large enough to work on; else it won’t be cost effective. In the case of expensive minerals, the situation is different. Small deposits can work in places where the transport cost is low.

Mining method

Open-cast mining is the cheapest and shaft mines are the most expensive ones. The cost also depends on the how large scale the operation is. If the mining is done at a large scale, then the capital and running costs can be low.

Accessibility

The accessibility of places where the mining operation will take place is important. The climate and topography tells whether the mining operation will be accessible or there will be obstructions.

Transportation facilities

Transportation facilities are important for successful mining. The easier and less expensive it is to transport the minerals to the sites of their use, the better it is.

If a place has a trace of minerals, it doesn’t guarantee that it can be exploited. Many times, they are only available in small amounts and so won’t be of much use. These factors are considered before starting a mining exploration.

Top 5 benefits of potash in our lives today

Potash contains potassium in a water-soluble form. Before exploration was used to obtained potash, it was acquired by leaching wood ashes in a pot and was used for manufacturing glass, soap and gunpowder. In the modern days, these minerals are mined and processed to compound potash that has more uses. Here are the benefits of potash in our lives.

Fertilizer

Plants need nitrogen, potassium and phosphorous to grow. Potash has soluble potassium and so is good for agricultural fertiliser. It improves the overall health of the plant. It makes the root of the plant stronger, resists diseases from occurring, and improve the yield rates. It ultimately improves the texture, colour and taste of food.

Animal feed

Potassium carbonate is used as animal feed. It is added as a supplement to improve a number of nutrients in the feed. So, it improves the health of animals. It can also increase the milk production.

Food products

It is used as general additives in food industries. It is included as a food seasoning. It is used for brewing beer as well. It has similar properties to baking soda and can be used to make gingerbread or lebkuchen.

Soaps

Caustic potash or potassium hydroxide si used to make soap. These soaps have better solubility and so needs less water to liquefy.

Glass manufacturing

Potassium carbonate is used as a flux, and it lowers the temperature at which the mixture melts. It gives excellent clarity to glass. So, it is used to manufacture eyeglasses, computer monitors, glassware, etc.

Potash has many other uses. The demand for potash is always huge in many industries. Ways to explore more potash is underway to keep up with the demand.
