Nine-month testing of pipe made with the new concentrate at
pressures exceeding 1250 psi at 73 F for water pipe and 140 F for gas reportedly show that the 45% concentrate performs as well as the standard 35% formulation on the market.
TSX VENTURE:DIB) is pleased to announce a record month in terms of production and sales of concentrate at
its pilot-mining program at the Bolivar mine in Chihuahua Mexico.
Two-mil-thick LDPE film samples containing this concentrate at
letdown ratios up to 12:1 reportedly have met the requirements of MVSS 302.
A further 3% copper reported to the nickel concentrate at
11% recovery, to bring total copper recovery to 85%.
Several passes through the Centrifugal Jig will be necessary to produce a 90 percent total heavy mineral concentrate at
the mine site.
In addition, recent bench-scale lab work has been successful in reducing the lead in the bulk concentrate by gravity methods thereby upgrading the copper content of the bulk concentrate to +25 per cent copper (from 20 per cent) and concomitantly yielding a saleable lead concentrate at
50 per cent lead.
