  • Placer deposit

    In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary process The name is from the Spanish word placer, meaning "alluvial sand" Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush...

  • Heavy Mineral

    Heavy mineral concentrates from drainage sediment and glacial till have turned out to be gainful as geochemical and mineralogical guides to gold and diamond exploration Microprobe analysis of heavy minerals aids in distinction between diamondiferous kimberlite pipes and those devoid of diamonds...

  • The Rise of Frac Sand and Mineral Exploration

    The economic tremors of the US shale boom have given a boost to mining and exploration for a few different minerals Drilling grade barite and bentonite prices have been rising, but there is another commodity that has seen a massive rise in demand, pricing, and new mine development: FRAC SAND...

  • Mineral Sands Projects

    Previous exploration by BHP in the early 1990s outlined large, low grade (10 -15% HM) heavy mineral sand deposit covering an area of 30km 2, and extending from near-surface to depths of typically 30-45m Further drilling by Sheffield shows the mineralisation is up to ,...

  • Heavy mineral sand

    Heavy mineral sand is a natural mineral concentrate which is often mined commercially Zircon, gold, ilmenite, rutile, monazite, and cassiterite are some noteworthy heavy minerals that are often extracted from sand Heavy mineral sand is not rare, but its area of occurrence is usually limited...

  • Fungoni Heavy Mineral Sands Project

    The Fungoni heavy mineral sands project is estimated to hold maiden ore reserve of 123Mt containing 480,000t of total heavy mineral (THM) grading 39% Mining and ore processing at Fungoni Conventional open-pit dry mining will be applied at Fungoni, wherein the free-dig unconsolidated sand will be mined using an excavator...

  • SPL 1495 Sigatoka Ironsands Project

    Exploration confirmed the presence of magnetite and other heavy minerals in the Sigatoka sand deposits, and exploration by Dome has now quantified an initial resource Magnetite as a source of iron for steel making has plenty of potential Its concentrates command a premium over the price of bulk iron ore because of its purity and use, for ....

  • Heavy Minerals

    Heavy minerals sometimes get naturally concentrated as a heavy mineral sand and there were, of course, no bromoform involved It was moving water either in a stream or beach that did the job Sometimes the sand is so concentrated in heavy minerals that it has a real economic value as an ore Sand collectors also love these black sand deposits ....

  • Geophysical response of heavy

    Geophysical response of heavy-mineral sand deposits at Jerusalem Creek, New South Wales D F Robson and N Sampath Introduction BMR has started evaluating how geophysical methods might assist in exploration for deposits of the heavy minerals rutile, zircon, ilmenite, and monazite...

  • Titanium Sands Company Projects

    Heavy mineral sand concentrations occur along the modern sandy shorelines of Sri Lanka in a number of places along the north eastern and north western coasts The heavy minerals have been transported to the coast by river systems from ancient metamorphic rocks that form the hilly interior of the island...
