preparedll Concentration of Gold in Seawater

2017-1-4  Gold in seawater concentrate (200Be) was concentrated by reduction with Cr(II) salt solution. Spectrographic analysis of the reduced mass showed 10X 10-6 g gold/litre seawater. GOLD and the other trace elements are present1 in seawater in so small quantities that their direct precipitation is not possible. They are re­
