Utilization of soluble starch as the depressant to flotation separation of pyrite from arsenopyrite

Jincheng Ran et al.

Summary: In this study, a macromolecular organic depressant soluble starch (SS) was introduced and its application and depression mechanism in the selective flotation separation of arsenopyrite and pyrite were investigated. Even a low concentration of SS can be stably adsorbed on the surface of pyrite through chemical adsorption and hydrogen bonding, and its poor flotation performance was determined by the formation of hydrophilic Fe-hydroxylated species. The arsenic-rich surface formed by arsenopyrite oxidation provided rich sites for the adsorption of the -OH group of SS, so as to protect the Fe sites from being shielded by metal-hydroxylated species. Given its low dosage and environment-friendly characteristics, SS is a promising flotation depressant with remarkable application prospects to remove arsenopyrite from pyrite concentrate.

A Comprehensive Recovery Process for Selective Separation and Enrichment of Copper, Zinc and Iron Minerals from a Polymetallic Ore and the Adsorption Mechanism of Collector Z-200

Bin Xu et al.

Summary: A comprehensive recovery process for selective separation and enrichment of copper, zinc, and iron minerals from a polymetallic ore was developed and showed promising industrial application prospects. The adsorption mechanism of the copper collector Z-200 on the surfaces of chalcopyrite, sphalerite, and magnetite was also investigated, demonstrating that Z-200 chemically adsorbed on the chalcopyrite surface through normal and back donation covalent bonds. This chemisorption was supported by the FTIR spectrum analysis result.

A novel sulfur-containing ionic liquid collector for the reverse flotation separation of pyrrhotite from magnetite

Qinzhi Yuan et al.

Summary: A novel sulfur-containing ionic liquid (SCIL) collector was synthesized and used for the selective separation of pyrrhotite from magnetite. The results showed that SCIL exhibited excellent collecting ability and selectivity, reducing the impurity content effectively. The adsorption mechanism analysis revealed that SCIL could chemisorb onto the pyrrhotite surface.

Online Superficial Gas Velocity, Holdup, and Froth Depth Sensor for Flotation Cells

Claudio Leiva et al.

Summary: In the flotation process, controlling froth depth and gas flow rate is crucial for improving efficiency and selectivity, but accurate measurement of these parameters is difficult. To address this issue, an intelligent online gas dispersion sensor based on two concentric cylinders has been proposed to improve the accuracy of gas velocity calculation and reduce the errors in froth depth measurement using pressure transducers.

Physical-chemical study of IPETC and PAX collector's adsorption on covellite surface

Yesica L. Botero et al.

Summary: The adsorption mechanisms of the collectors IPETC and PAX on a covellite surface were studied through microflotation tests, FT-IR, XPS, and DFT calculations. The results showed that both collectors have a significant impact on covellite flotation and that the flotation is not pH-dependent.

Surface chemistry investigation of froth flotation products of lead-zinc sulfide ore using ToF-SIMS and multivariate analysis

Hao Lai et al.

Summary: This study investigated the surface chemistry differences between minerals in lead concentrate and tailings in complex flotation circuits of lead-zinc sulfide ores. The results showed that the adsorption of lead ions onto specific mineral surfaces was an important reason for the failed separation of minerals from galena. The surface chemical evidence provided by this study helps to better understand the selective separation mechanism of lead-zinc sulfide ores.

New insights related to the flotation of covellite in porphyry ores

Yesica L. Botero et al.

Summary: Covellite flotation can be influenced by collector type and dosage, while high PAX concentration and low pH are suitable for bulk flotation, and low IPETC dosage and high pH are optimal for selective flotation. Selective flotation of covellite is feasible with IPETC at alkaline pH with low dosage, while bulk flotation is achievable with PAX at pH 8 with high collector concentration. Covellite recovery remains constant over a wide range of pH values, allowing for selective separation from other sulfides such as pyrite.
