The development of automated methods for the digestion of rocks and minerals without human participation (Robotic Stations) must continue. This will facilitate and accelerate one of the most time-consuming steps of the whole geochemical analysis process (from a solid sample to a sample solution form to instrumental analysis).
The solid minerals and mining sector contributed a paltry 0.5% to the Gross Domestic Product (GDP) in 2018, with annual production averaging 40 million metric tons valued at about 34 billion naira ...
Calcite (CaCO 3) is the main long-term sink for carbon and is one of the most abundant minerals in Earth's surface environment.It is therefore of prime importance in the global carbon cycle. It also helps to regulate the chemistry of aquatic environments (), scavenges trace and heavy metals (), and records paleoenvironmental conditions ().One …
Solution mining is a mining method of dissolving and extracting minerals by injecting fresh water into underground deposits and taking advantage of the characteristics that halite, potassium salt, trona, and mirabilite that are easily soluble in …
Solid solutions are a topic of interest for many fields of materials science, from metallurgy to geology, and there are examples in many different classes of …
Mineralogy is thought to be one of the earliest fields of science. Like plants, animals, and water, minerals (and rocks which are most typically solid aggregates of one or more minerals) have always been resources readily available to hominids (any of the ancient family of erect bipedal primate mammals, of which only Homo sapiens exist …
