    Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation

    collecting rocks on ocean beaches: what to look for and

    Even though it’s fairly common and affordable today, historically, jasper was a very valuable stone. When rockhounding this type of beach stone, look for surfaces on the stone that are shiny when wet, but dull and porous when dry. The most common color of jasper that I’ve experienced are yellow and tan

    ore mineral- an overview | sciencedirect topics

    Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm

    Gravity methods use the difference in the density of minerals as the concentrating agent. In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon)

    the basics of logging core for exploration

    Groupers are core loggers who will tend to group similar units more readily, especially in known ore zone areas. If you know where an ore zone is the stuff outside becomes of less important. The advantages to this type of logging is speed, one can log a lot of core by only prioritizing known good zones and grouping known un-mineralized zones
