Searching for deposits of natural resources. When we pick up any object, very few people realize how it happened, that it even came into being, and that it can be useful to us. It doesn’t matter if it’s about tools or, for example, game consoles. Usually, we consider the presence of all objects in our environment as something normal and we are actually used to it, without thinking at all about how the enormity of work and how much knowledge and technology must be used often to do even simple things . Let’s take a look at what it looks like in reality.

Searching for deposits of natural resources

The first thing we need to know is that everything we use to make tools or other everyday objects (small or large) begins as a raw material. The raw material may be of natural or so-called natural origin (i.e. wood and, in the later past, animal bones) or of mineral origin, i.e. iron, steel, gold, diamonds, etc. (in short, everything that we can dig out of the ground and is part of the inanimate part of our world). The search for deposits of natural resources is currently an extremely important issue. Primarily because our resources are dwindling. The search for deposits of natural resources must now be much more precise. First of all, because the current deposits, which have never been exploited before, they are usually much less abundant, so the research must be carried out more precisely and actually faster.

The search for deposits of natural resources can of course be done better and more accurately than in the past, if only because the techniques used to search for deposits of natural resources have changed significantly. In the past, the main method of searching for deposits of natural resources was to drill a large number of boreholes. Currently, we can use ultrasound, electromagnetism and a whole range of other methods for this purpose.that the techniques used to search for deposits of natural resources have changed significantly.

Raw material processing

Obviously, the extracted raw material cannot be used immediately. Very often it does not really resemble its final version, i.e. a semi-finished product that comes out of the steelworks in the form of sheets or bars. Virtually all metals, except precious metals, are very rarely found in metallic form in nature. They are most often associated with other elements in the form of minerals. For example, iron is in the form of pyrite or ferrite. Copper is also very rarely found in a metallic form, therefore it is impossible to locate the deposit alone for someone who is not familiar with geology. In addition, the ore is processed, which must take into account all the elements and minerals contained in the ore, as some of them can help and some hinder processing. Metal smelting alone,which of course does not have to be the only successful process (as there are now also, for example, Hydrometallurgical methods for producing metal) this is not the end of the process. In many cases, for example, the metal must be additionally electro-refined in order to achieve the required purity. For example, electrolytic copper, which is used in electrical cables, must have a purity of 99.9%, and only electrorefining can provide such purity.

If the amount of impurities was greater, the conductivity of copper would drop significantly, while the resistances would increase, which translates, firstly, into energy losses, and secondly, that such conductors would simply heat up significantly more.

Machining of semi-finished products

The semi-finished product in the form of sheets, discs or bars is then sent to plants that have to process them in some way using various methods in order to give this material the required final form. Many different processes are used in these plants, for example, precision punching on hydraulic presses, milling, cutting, and deburring. For example, hardening of such a material or even thermo-chemical treatment, i.e. hardening combined with carbon-nitriding, is very often required.

The heat treatment itself in a quench furnace does not necessarily have to be the final step either. Very often, there is also a final surface treatment to remove burrs and sharp edges, or the tempering technology, consisting in relaxing stresses in the material, in order tothat it does not crack under any kind of impact load, and that it is as strong as is expected of the material. The final element in the creation of a finished product is putting together many parts, coming from various processes and very often from different materials. Varnishing it, packing it and sending it to the customer. As we can see, producing even simple things requires a lot of commitment and the use of knowledge and technology from a wide range. It is therefore the result of the development of technology over the years, and sometimes millennia.
