Research on dosage matching for gold and antimony froth flotation
A new method of flotation dose matching is proposed based on rough sets and case-based reasoning, realized the control of reagent adding in floatation process. This method has Thus, we investigated the relationship between reagent addition, feed conditions (including ore properties, slurry density, and slurry flow rate), and froth image features based on the mechanism of froth Two-Step Optimal-Setting Control for Reagent

Improved recovery of a low-grade refractory gold ore using flotation
Abstract. In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results This method also efficiently accounts for the influence of disturbances on the flotation system and improves the stability and effectiveness of the flotation system.

90% of gold can be recovered by conventional cyanide leaching. Refrac-tory ores give low gold recoveries or give acceptable gold recoveries only with the use of signifi cantly more reagents or more complex pre-treatment processes. 1 Generally, placers, quartz vein gold ores, oxidized ores, and silver-rich ores are free-milling and 1000 g of mill product (65% solids) was used for the floatation tests. A Denver floatation machine, a 3 L floatation cell and tap water were used for the batch floatation tests. Selective and bulk floatation experiments were carried out at about 30% solids. The impeller speed was set at 1800 r/min. In the first and second stages the pH Improved recovery of a low-grade refractory gold ore using

Flotation Reagents. mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses. Flotation as a concentration process has been extensively used for a number of years. However, little is known of it as an exactElectrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide Preparation of Antimony Sulfide and Enrichment of Gold by

Handbook of Flotation Reagents: Chemistry, Theory and Practice
The flotation of gold-bearing ores is classified according to ore type (i.e., gold ore, gold copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery of gold from different ores is vastly different. In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation ofSimilarly the bio-oxidation by an iron- and sulphur-oxidizing bacteria accounted for 91.4% gold extraction from a pyritic ore (20% S) as compared to 73.0% observed in the direct cyanidation of the same sample (Mubarok et al., 2017). Therefore, the bio-oxidation of these gold-antimony sulphide materials was successful. 4. DiscussionBio-oxidation of refractory gold ores containing stibnite and
