The need to explore more complex and low-grade silver ores and to develop novel and cost-effective processes to recover silver from waste is becoming an important challenge. This paper aims to characterize old, low-grade, silver tailings generated by the former Zgounder silver mine, located in Morocco. Understanding the mineralogical composition, particularly the …
Rule et al. (2008) in a pilot investigation found that at stable primary plant operation, tertiary tailing re-treat flotation recovery from the primary plant tailing stream yields an average of about 10% value recovery; while at unstable plant operations, the tertiary re-treatment flotation recovery reaches about 25% relative to the tertiary ...
For Q4 2024, the tailing filter area, which was turned over to the mechanical contractor in early October, will allow focus on installing at least one tailing filter along with the concentrate ...
Tailing Filtration Area - More than 75% of the floor slab and of the filter bearing wall for the tailing filter building has been poured. ... The Bolanitos operation encompasses three underground silver-gold mines and a flotation plant. The Terronera project is located 40 km northeast of Puerto Vallarta in the state of Jalisco, Mexico ...
This residue was then combined with the flotation tailing for a final stage leach maintaining 1 g/L NaCN for 24 hours. Overall, the combined testing showed that gravity pretreatment yielded a gold recoveries ranging from 17% to 38%. The silver recoveries were typically lower, ranging from 2% to 10%.

The ultimate increase will depend on the ratio of concentration obtainable by flotation with a flotation tailing that can be economically discarded. This ratio and consequent increase may range from 2:1 up to 35:1. …
cyanidation of the flotation tailings indicate that 70-75% of the gold and about 15% of the silver contained the concentrator tailings can be recovered by agitated tank cyanide leaching.
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
