Abstract

ine"> </The effect of the use of Cuban crude in the process of leaching, sedimentation and distillation of
the processed minerals at “René Ramos Latour” Company was evaluated. Two periods of tests
were performed; one when oil was introduced into the furnace by spear and the other when it
was introduced by spear and chamber. The results demonstrated the feasibility of using the
Cuban crude in reduction and leaching process of mineral by the use of spear and chamber as
well. Nickel and cobalt extractions achieved by stepwise exceed values found in the related
literature. Deposition of mineral was good reaching values of 1,736 -1,745 kg/m3 at the bottom
of the sedimentation stage leach and 1,774 -1,807 kg/m3 in the washing stage. The thickeners
were maintained with high clear liquor level throughout the test with values between 28,0-30,0
ppm. The sedimentation rate achieved low values both in the first and in the second leaching
stage. Sedimentation unit area was 0,23 m2 /T day, so that no sedimentation problems were
presented. It was observed an increase in the sulfur content up to values of 6,52 g/L for a nickel
content of 12,0g/L, which caused that the dissolved nickel in downloading stills were of
0,392 g/L and 2,58 g/L of ammonia. The sulfur content in the nickel carbonate was increased up
to 6,30 %, which is 2,5 % higher than conventional.
