In Alaska, ore samples from mining properties were processed using Knelson concentrators. In one case, material originally evaluated at $5.00 a cubic yard yielded over $12 a yard in recoverable gold when tested with a Knelson concentrator. In a second case, the recoverable gold value increased from $3 to $30. According to CSMRI …
At Peñoles Tizapa mine in Mexico, the installation of Knelson concentrators resulted in a net increase in overall gold recovery of more than 10% (Espinosa et al., 2011). Another case is Marvel Loch ( et al., 2011 ), where the installation of a Consep Acacia to upgrade Knelson batch concentrate resulted in an increase in overall gold ...
Knelson Concentrators Africa differed from Peacocke & Simpson in that its primary purpose was to conduct testing, sales, commissioning and after-sales service for Knelson Concentrators. Whereas P&S was, and is, a mineral testwork specialist company that also represents a number of mineral equipment ranges.
