“…As shown in Figure 9, the contact angles of water on pure calcite and cassiterite were 35.17 ± 1° and 40.70 ± 1°, consistent with previous reports [34,35]. After the interaction between minerals and citrus pectin, the contact angle of the cassiterite sample increased to 50.15 ± 1°, signifying the enhanced hydrophobicity of the cassiterite surface due to the action of citrus pectin.…”

This paper presents the development of an environmentally friendly, small molecular depressant citrus pectin for improving the recovery of cassiterite resources. Citrus pectin extracted from citrus peel was utilized as the depressant, and it demonstrated significant potential in separating calcite from cassiterite in micro-flotation tests. The molecular weight of the citrus pectin extracted in this paper decreased from 11,485,412 Da to 32,959 Da compared to commercial pectin, resulting in the depressant efficiency of the reagent. The results of a zeta potential and adsorption test indicated that citrus pectin had less and weaker adsorption on the cassiterite surface and could be replaced with NaOL. The chemical adsorption process of citrus pectin on the surface of calcite was determined through FTIR spectroscopy analysis. XPS analysis results indicated that the interaction between the carboxyl groups of citrus pectin and calcium atoms enables adsorption to occur. The AFM revealed that citrus pectin displayed a uniform and dense pattern of point-like adsorption on the surface of calcite. Micro-flotation experiments showed that cassiterite recovery of 80% can be obtained at a citrus pectin dosage of 10 mg/L. Citrus pectin has the advantages of being low-cost, highly selective, and environmentally suitable, making it a promising alternative to conventional reagents.

“…The flotation of lead vanadate minerals, as well as flotation of non-sulfide minerals, is very sensitive to the ionic composition of the flotation pulp [36,57,74,88]. The influence and corresponding retarding mechanism of the ionic composition on flotation, mineral surface properties, and surface chemistry of non-sulfidic minerals as well as oxidized base-metals minerals are well observed and described in modern scientific works [89][90][91][92]. The main sources of various unavoidable and harmful ions in flotation pulp are the dissolution of soluble minerals and salts from ore, the release to solution through the grinding process, and used process water.…”

Vanadium has been strongly moving into focus in the last decade. Due to its chemical properties, vanadium is vital for applications in the upcoming renewable energy revolution as well as usage in special alloys. The uprising demand forces the industry to consider the exploration of less attractive sources besides vanadiferous titanomagnetite deposits, such as lead vanadate deposits. Mineral processing and metallurgical treatment of lead vanadate deposits stopped in the 1980s, although the deposits contain a noteworthy amount of the desired resource vanadium. There has been a wide variety of research activities in the first half of the last century, including density sorting and flotation to recover concentrates as well as pyro- and hydrometallurgical treatment to produce vanadium oxide. There have been ecological issues and technical restrictions in the past that made these deposits uninteresting. Meanwhile, regarding the development of mineral processing and metallurgy, there are methods and strategies to reconsider lead vanadates as a highly-potential vanadium resource. This review does not merely provide an overview of lead vanadate sources and the challenges in previous mechanical and metallurgical processing activities, but shows opportunities to ensure vanadium production out of primary sources in the future.

“…According to the literature, the solid waste obtained from Litsea cubeba kernels contains ~25% of Litsea cubeba kernel oil, which mainly contains 10 and 12 carbon fatty acids. Furthermore, hydroxamic acid with medium and long carbon chains (8–12 carbons) has been widely used in mineral flotation, corrosion inhibition, and other chemical industries [ 14 , 15 , 16 ]. Therefore, Litsea cubeba kernel oil is a suitable raw material for the preparation of hydroxamic acid, which also provides a new way to utilize Litsea cubeba kernel solid waste.…”

Litsea cubeba is a characteristic woody oil resource in Hunan. As a solid waste of woody oil resources, Litsea cubeba kernels are rich in Litsea cubeba kernel oil with a carbon chain length of C10–12 fatty acid. In this work, aliphatic hydroxamic acids (AHAs) with carbon chain lengths of C10–12 were prepared from Litsea cubeba kernel oil via methylation and hydroximation reactions. The adsorption and hydrophobicity mechanism of AHA towards wolframite was explored by contact angle, zeta potential, Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The flotation results demonstrated that AHA was a superior collector than the traditional collector such as benzoyl hydroxamic acid (BHA). Zeta potential and contact angle results have shown that AHA was adsorbed on the surface of the Fe(III)-activated wolframite in its anionic form, which significantly improved the surface hydrophobicity of wolframite. FTIR and XPS revealed that AHA was chemically adsorbed on the surface of Fe(III)-activated wolframite in the form of a five-member ring, which made the hydrophobic chain reach into the solution, come in contact with bubbles, and achieve flotation separation.
