Copper production was 4.5% over guidance due to higher grades from fresh tailings and higher grades and recoveries from historical tailings ("Cauquenes tailings"). Amerigo's 2023 annual copper production guidance is 62.3 M lbs. Quarterly molybdenum production was 0.3 M lbs, 5.2% over guidance.
About the Zuun Mod Molybdenum-Copper Project. ... Based on an average grade of 0.06% Mo and similar copper grades it is reasonable to expect that an overall molybdenum recovery of 85-87% to a concentrate grade of 52% Mo is achievable and a copper recovery of at least 75% would be expected to a 25% Cu concentrate. The Q2 …
Second, sewage effluent caused a small but significant loss in copper recovery and a large loss in molybdenum recovery. Removal of surfactants from sewage effluent by fractionation eliminates the unmanageable froth but has no effect on the loss in metal recovery.

According to the results from laboratory studies, increasing the dosage of starch from 0 to 1000 g/t increased the recovery of molybdenite flotation and reduced the access of copper minerals to molybdenite concentrate. In this case, molybdenum recovery (in lab tests) is increased by about 5% compared to the case of not using starch.

In the copper-sulfur separation operation, due to the large amount of lime and the fine grinding particle size, it has a greater impact on the corresponding flotation of molybdenite; in the actual copper separation operation, the copper recovery rate is …
Q1-2023 copper production of 16.5 million pounds, 4.5% over guidance. Q1-2023 cash cost 1 of $1.91 per pound, 11% lower than guidance due to strong molybdenum credits. $5.5 million returned to ...
FIRST ROUND: COPPER RECOVERY IMPROVEMENT. A blend of dithiophosphate (DTP), thionocarbamate (TNC) and mercaptobenzothiazole (MBT) were added to the SIPX …
In this case, the recovery of copper to molybdenum concentrate is in the lowest possible amount compared to other cases. This is also confirmed in the recoveries obtained for molybdenum because according to Fig. 8, the highest grade and recovery for molybdenum at a concentration of 1000 g/t of starch have been obtained. According to …
In this paper, prediction of copper and molybdenum grades and their recoveries of an industrial flotation plant are investigated using …
