  • Extraction Development For The Separation Of Gadolinium

    Jul 21, 2020 Xenotime sand, a byproduct of the tin mining process of PT Timah, is one of the potential gadolinium Gd resources. Because of similarities in their physical and chemical properties, it is difficult to separate and purify Gd from rare earth elements REEs in xenotime sand i.e., yttrium and dysprosium. In the present work, Gd was separated through an extraction process using Cyanex 572.

  • A Poor Mans Method Of Smelting Gold Sciencing

    May 22, 2018 Any cast iron vessel will do, or you could create your own special design using a delft casting method. This method incorporates simple clay sand casting with precision design including pouring channels. The compact nature of the sand doesnt allow the liquid gold to push its way down and thus it pools and cools in the cast.

  • Bacterial Consortium For Copper Extraction From Sulphide

    Oct 30, 2013 The economic extraction of copper from low-grade ores requires low-cost processing methods such as in situ, dump and heap leaching. Bacterially assisted heap leaching of low-grade copper sulphides is a developing technology that has been applied successfully for the extraction of copper from secondary sulphide minerals such as chalcocite at a ...
