Reagent Predictive Control Using Joint Froth Image Feature for Antimony
Then a model predictive control is applied to validate the proposed froth image feature in section 5. Section 6 concludes this paper. 2. ANTIMONY FLOTATION PROCESS DESCRIPTION In this paper, a real gold-antimony flotation plant located in Hunan, China is discussed. The focus of the discussion is the antimony flotation process, Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as Antimony Recovery from End-of-Life Products and Industrial

Data-driven-based adaptive fuzzy neural network control for
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 With the vigorously growing demand of the steel industry, corrosion resistance alloys, clean energy industries, and a variety of engineered infrastructure or technology, high-grade nickel ores are being exhausted gradually in the world. This review outlines metallurgical processes for nickel production from various nickel sulfide ores Comprehensive Review on Metallurgical Upgradation

Geochemical distribution of selected elements in flotation
Materials held within mine tailings pose a serious risk to the environment in cases of tailings dam failure. Collapse of the tailing dam at the Stolice antimony mine in West Serbia caused a spilling of tailing slurry into the nearby river watersheds. Medium-term effects of As, Pb, Sb, Zn, and Cd from the tailings material that remained in the flooded The largest Russian antimony ore deposits are reviewed analytically. The present-day physicochemical methods (nuclear quadrupole resonance, X-ray electron spectroscopy, multinuclear (13C, 15N, 31P) NMR) are used to develop innovative technologies. The innovative process for treatment of Au-Sbores of the Sarylakhsky and Innovative processing and hydrometallurgical treatment

Shape-weighted bubble size distribution based reagent predictive
Antimony flotation is a complicated industrial process with an unknown system structure. Manual manipulation is still widely used by observing the froth appearance, which relies on operators’ experience. Therefore, this paper proposes a reagent predictive control strategy for the antimony flotation process based on machine The content of the antimony ore is the most important point for determining the area of usage. so called factorial design, has been used to determine the main and interacting effects of(PDF) THE BENEFICIATION OF ANTIMONY ORE BY FLOTATION
