Reservoir geology – science in business. When preparing for a mining investment, we have to answer a lot of questions. Reservoir geology is a field of science that deals with the answers to these types of questions. The average person on the subject of mining has more or less the following view: a geologist comes to the research site, takes samples, then triumphantly states that the mineral is sought and we start mining. The reality is definitely more complicated, especially since most elements do not exist in the form of beautiful shiny lumps or veins.
What is reservoir geology?
Reservoir geology deals with the geology of natural deposits. At the same time, it is a field of science that, in addition to providing, for example, the usual geological composition of a given deposit, is able to assess how profitable the extraction will be or what problems we may encounter during extraction. Mining itself is also not everything, because most ores are not in a pure state and need to be properly processed so that they can be used.
Few people know that, for example, when mining gold or iron, very rarely (or at least currently) we deal with deposits in a metallic state. What we can see in movies, for example about the gold rush, is of course true, but this type of ore and in this form is extremely rare and only in specific conditions. If we want to mine iron, copper or gold on a large scale, we must learn to find deposits that, at first glance, do not contain this metal at all, but are various types of chemical compounds of the sought metal with other elements.
What questions does reservoir geology need to answer before mining begins?
Of course, in the first place, deposit geology must answer the question of how large the deposit is, how deep it is, and what percentage of the sought-after material is, for example, in a ton of material that will have to be extracted. Very often it turns out that although the deposit theoretically has a lot of the sought-after element, it is so dispersed that its extraction is not profitable. Currently, this situation is much less frequent, because the prices of ores or rare earth metals are currently very high, so even at first glance, poor deposits are profitable to extract, but still, for example, 50 years ago, some deposits were not considered at all attention.
Reservoir geology and re-analysis
Currently, deposit geology also deals with such issues, such as re-analyzing the resources of deposits that have already been explored or where exploitation has been discontinued. In the first case, as mentioned above, in the past years, the lack of profitability of the mining investment was assessed, while in the second case, there is a certain moment when, for example, it was necessary to dig much deeper than before or the ore became poorer, which also translated into a lack of sense economic extraction. Currently, because raw materials are definitely in price, and technologies are more effective and efficient, some deposits, theoretically once completely useless, are exploited. Reservoir geology most often has to re-examine these areas in order to.
Deposit geology and ore processing
Deposit geology, in addition to determining the feasibility of mining, also has other tasks, which in some situations are very important. The best example of this are the Polish copper deposits. Polish copper deposits, although they are very large (one of the largest in the world), also have a huge disadvantage, namely they are deposits that are called polymetallic. In addition to the most sought-after copper, these deposits contain a lot of, for example, silver, metals of some rare earth metals and sought-after valuable heavy metals. Theoretically, one could say that this is a kind of boon, but contrary to appearances, it is also a big problem.
Each of these metals is obtained by different methods. This is often irreconcilable. In addition, Polish deposits are quite heavily polluted with organic material, which is coal. Coal interferes with the copper smelting process in the blast furnace, making the process much less efficient than it could be. Reservoir geology should anticipate such situations, react to them and inform them. Especially if very large investment expenditures are involved, which, as we know, everyone would like to pay back as soon as possible. For this reason, deposit geology is a very responsible and, on the other hand, exciting job. Ironically, very few people in our country deal with reservoir geology, which may make choosing a career path that will go along with reservoir geology a pretty good idea, especially for people who.
