Techniques Used In Mining

Mining is the process of extracting precious minerals or other geological resources underneath the earth’s surface and they usually come from a seam, a vein, an orebody or a lode. More often than not, these deposits interest a miner for economic reasons. That is why they go through the tedious process of mining just to get it. Examples of ores that have been recovered in the past by miners are dimension stone, gravel, coal, oil, gemstones, metals, shale, potash, clay and rock salt. Mining is usually the recourse when the material needed cannot be artificially made inside a factory or a laboratory or if it cannot be grown and harvested via agricultural means.

The mining process is divided into two digging types: there’s the surface mining and the sub-surface or underground mining. At present, the former is more common compared to the latter and eighty five percent of the minerals we see today, which includes natural gas and petroleum are extracted through the surface mining technique. The same technique goes for all ninety eight percent of all metallic ores.

Let’s talk more in depth about surface mining and sub-surface mining.

Surface mining is a performed to remove or strip of surface dirt and vegetation. If there is a need, it will also remove bedrock. The reason for this is pretty obvious, so the miner can access ore deposits that are buried underneath. The techniques utilized in surface mining are the following: open-pit mining. Open-pit mining recovers materials from the name itself, an opening in the ground. Another example technique known in surface mining is quarrying. It is more or less similar to an open-pit mining only that it involves clay, stone and sand. Strip mining is another technique in surface mining and it involves ‘stripping’ the outer layers to gain access to seams and ores underneath the surface. Another common technique is called mountaintop removal. This is pretty much self-explanatory and it’s usually implemented for coal mining. This technique consists of removing the top layer of a mountain to gain access to ore deposits. And then there’s the landfill mining. This technique involves landfills that are dug up and processed.

Sub-surface mining is the second technique, which involves digging up shafts and tunnels into the ground so the miners can reach ore deposits buried underneath. It is through these shafts and tunnels that waste rock and ores are brought up into the earth’s surface. Sub-surface mining are classified according to the shafts used or the technique or method utilized to get to the ores or mineral deposits. Slope mining is a category that makes use of sloping shafts. Drift mining makes use of horizontal tunnels whereas shaft mining makes use of vertical shafts.

One very important thing to remember in mining is safety. Mining is a dangerous job because it necessitates accurateness. That is why you need to equip yourself not only with knowledge but also with the protective gears needed to do these processes and techniques as well as SCADA and other IIoT systems.

Turning Mined Quartz And Sodium Carbonate Into Glass

Glass is pretty amazing. It can give us protection but it can also be easily broken. The material it’s made out of is opaque in quality but when it turns to glass it becomes see-through. It is solid but it also has liquid properties. Glass is everywhere. From your mirror to your window to your prescription glasses. We use glass often if not all the time. It’s one of the first materials we’ve manipulated.

How is glass made? Quartz that is usually in the form of sand is heated to its melting point where it then transforms into a liquid state. It has to be at the temperature of about 2000 degrees Celsius. When it is cooled, it doesn’t revert back to it’s sand-like state. It becomes like a solid liquid which is transparent. Solid liquid means that it is a liquid but its molecules move so slowly that you won’t notice it move with the naked eye. If you look at glass panes from houses that are a hundred years old, you’ll notice wavy lines in the glass. That shows the slow movement of the glass molecules. When new, the glass would have no lines.

Glass is awesome because it’s cheap to make, easy to shape when melted, and it’s heat resistant. It also doesn’t react chemically with many substances. It’s great for storage purposes, especially for food. It’s also almost indefinitely recyclable.

The best way to make glass that’s more friendly to the environment is to mix quartz that’s in sand form with old glass that’s been used already. Sodium carbonate would be added to that along with calcium carbonate. All those are then put in an extremely hot furnace. The sodium carbonate helps make the melting point of the quartz and recycled glass lower so that it doesn’t require a lot of energy to run the furnace. The calcium carbonate makes the end product stable. The melted glass can then be put into moulds to make different glass products or it can poured out onto melted tin to make flat sheets of glass used for windows, doors, and mirrors. Glass can also be blown to make unique shapes. Companies like ALS Glass Works Brisbane use the glass produced for household applications like glass balustrades.

Coloured glass can be made by adding other chemicals to the main ingredients. To make it even more heat resistant, boron oxide is added to the melted sand. This heat resistant quality is perfect for making oven-proof kitchenware.

Good Painters Are Needed In The Mining Industry

The last thing you would’ve thought to need good painters is the mining industry. Usually when you think of mines, you think of coal, oil, gold, silver, copper, or other precious metals. You don’t usually think of painting. However, painting plays a very important part in the mining industry. How? The mining industries need professional painters not only for their office buildings, but they also need them for painting other structures related to their industry. Painters need to know how to paint (obviously), put on wallpaper, and put on other finishes on just about any surface. They also need to fix damages and prepare surfaces before painting or refinishing. An in-depth knowledge of each industry’s needs and specific safety regulations must be learned before consulting with customers and providing painting services. They must be good at calculating to get accurate measurements of surface areas that need to painted. The right tools are also important for them to be able to do their jobs properly and safely. They also need to know how to take off old paint correctly and prepare the surface areas for new paint that will last a lifetime.

There is a high demand for painters in the industrial sector. In the past, most painters were needed for residential purposes only but with the increase in industrial activity like oil mining, the need for industrial painters with a thorough knowledge, training, and experience in the industrial sector has risen.

To become a great painter in the industrial sector, one must get training by doing many jobs over many years. There is no better teaching tool than by experience. You’ll come across jobs that are unique and not found in textbooks. This will help you develop your problem-solving skills to see if you can complete jobs despite the challenges posed. It’s great to get an apprenticeship in painting for three to four years to be able to get the right training and education in this field.

The schooling part will teach important safety procedures related to each industry that must be implemented at each job so that you’ll be able to safeguard your life and those of others.

You’ll learn how to paint properly on any surface area required. You’ll learn the proper way to use tools for prepping and painting. You’ll learn to use different chemicals properly in relation to painting and learn what chemicals not to use when painting in certain volatile environments.

There is a lot to know when it comes to commercial and industrial painting. Good training and education is needed to become a master painter. However, it can be a rewarding and high-paying job if diligently done.
