The technological processing flowsheet for gold-bearing ores varies widely. The choice of a particular technological flowsheet depends on several factors, including the nature of the gold in the ore, especially its size and chemical composition, the nature of the minerals associated with the gold, the presence of other valuable components in the ore, and the …

Antimony toxicity in soils and plants, and mechanisms of its. Antimony (Sb) is a non-essential element for plants, animals, and humans. With increased anthropogenic inputs from mining and industrial activities, ore processing, vehicle emissions, and shooting activities, elevated Sb levels in the environment have become a growing concern.

Responding to this challenge, our research targeted secondary antimony sources from underutilized residues of gold, copper, and lead ore processing, which currently pose environmental concerns. Through meticulous experimentation, we determined that optimal antimony leaching is achieved at 120°C within 2 hours, using a 250 g/L Na2S and 60 g/L ...

In this paper, a real-world gold-antimony flotation plant in Hunan province of China is discussed. The simplified production flowsheet is shown in Fig. 1.It consists of two main objectives: (1) separate the gold from the raw ore in weak-alkaline environment, while the antimony particles are ensured to be non-floatable; (2) separate antimony under a …
