Toachi Announces Positive Metallurgical Test Results - Seite 2
Four composite samples representing the expected zones of the ‘La Mina’ mineralized horizons have been tested at SGS Lakefield. Following a program of some 55 Rougher/Scavenger and bulk cleaner tests, the results show that the La Mina VMS polymetallic mineralization responded well to a conventional flotation flowsheet and produced saleable grade concentrates. Locked cycle tests (LCT-1) was conducted on the sample composite of the zone 300.
The flotation test work showed good metal recoveries, creating saleable Copper/Lead and Zinc concentrates. Copper/Lead concentrate showed the following grades and recoveries:
|Cu||20 -23 %||88 - 90 %|
|Pb||4 - 5 %||70 - 72%|
|Au||13 g/t||41 -43 %|
|Ag||141 g/t||45 - 50 %|
Zinc concentrate showed the following grades and recoveries:
