Pocone Brazil Gold Production
Paul Baker, Mining Engineer, reports on the Pocone Gold Production as
follows:
VANCOUVER, British Columbia--(BUSINESS WIRE)--Aug. 19, 1998--
Development Plan
The Plan that has been followed was to build a Central Processing Plant
at the Urbano Project Site which could process the concentrates from
five 1,000 ton/day satellite flotation plants located in the Pocone
vicinity.
The Central Processing Plant is complete and contains a six-bedroom
house, a well-equipped laboratory and a 600 sq. meter workshop as well
as supporting the first of the 1,000 ton per day flotation plant. This
Central Processing Plant is now 100% complete and we are now fabricating
and building the second 1,000 ton per day satellite flotation plant.
Flotation Plants
Each flotation plant is designed to process 1,000 tons of ball milled
material per day. This material contains 0.3 to 0.5 grams per ton of
gold.
The flotation plants reduce this material to a 200:1 concentrate. For
each 1,000 tons of 0.4 grams per ton of material processed a 5.0 ton
concentrate of 75.0 grams of gold per ton is produced.
Pulp with a density of 40% by volume is made by adding 75,000 liters of
water per hr. to the plant feed material. Four inch diameter by three
inch diameter pulp pumps with a capacity of 2000 liters per minute are
used to inject the pulp into the column flotation units.
Since the flotation plant at the Urbano Project was completed, it has
been operated at 300 tons of ball mill material per day, one third of
its full capacity. This is the ''break even'' point for operating the
plant. Previously, the tailings dam area and the return water system
were not completed sufficiently to handle the full capacity of 1,000
tons of ball mill material per day (on hundred tons of pulp per hour) on
a continuous basis. The tailings dam areas and the return water system
are being upgraded to handle this full capacity volume.
Gold Production
Each flotation plant produces 300 grams per day (about ten ounces) of
gold. This gold is contained in the 5.0 ton concentrate.
Leach Plant
The gold in the concentrate is leached using a cyanide system. The time
required for leaching is twelve hours. The leach plant has a capacity of
150,000 liters, and is capable of handling the concentrates from five
satellite flotation plants. The concentrates from these satellite
flotation plants will be transported to the Central Processing Plant
located at the Urbano Project site.
Cost break-down
Each flotation plant costs approximately $1,100 US per day to operate at
a capacity of 800 to 1,000 tons of ball mill material per day. This cost
does not include amortization of the initial plant cost.
All required work at the Urbano Project to go to full production will be
achieved within two weeks.
