Mining Surface mining Britannica

Mining-Mining - Surface mining: It has been estimated that more than two-thirds of the world’s yearly mineral production is extracted by surfacemining. There are several types of surfacemining, but the three most common areopen-pitmining, stripmining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.

Introduction to Web Scraping withPython Stack Abuse

IntroductionWeb-scraping is an important technique, frequently employed in a lot of different contexts, especially data science and datamining. Python is largely considered the go-to language for web-scraping, the reason being the batteries-included nature of Python. With Python, you can create a simple scraping script in about 15 minutes and in under 100 lines of code.

Mining Prospecting and exploration Britannica

Mining-Mining - Prospecting and exploration: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, and location with respect ...
