Major Mines Projects Cerro Lindo Mine

Cerro Lindo is a Kuroko-style VMS deposit with economic grades of Zn Cu Pb and Ag. Mineralization is hosted by a pyroclastic unit composed of ash and lapilli-type polymictic tuffs with subrounded well classified fragments. Some lapilli have centimetre-scale pencil-like shapes due to development of an incipient schistosity.

Multiple Factors Influence the Accumulation of Heavy

 · The average (n = 40) total fractions of HCl-extractable metals in the O horizon were Cu 46 Ni 23 Pb 48 and Zn 34 in the A horizon these were Cu 20 Ni 5 Pb 22 and Zn 5 . Thus the fraction of HCl-extractable metal depends on the horizon specifically to the concentrations of organic matter and metals (Pb > Cu > Zn > Ni).

Degradation of Cd Cu Fe Mn Pb and Zn by Moringa

 · A mining company supplied the zeolite samples utilised. The crushed rock-like form of the original zeolite was ground as fine as possible using a crusher and a Ball Mill. It was further pulverised and sieved to obtain particle sizes of 63 μm. The zeolite was then submerged for 24 hrs in 1 M aqueous NaCl to enhance its cation exchange capacity.
