Adsorption performance and mechanism of the commonly used collectors with Oxygen-containing functional group on the ilmenite surface: A DFT study

Hongliang Zhang et al.

Summary: This study systematically investigated the coordination chemistry adsorption mechanism of commonly used collectors with oxygen-containing functional groups on the ilmenite surface using first-principles DFT calculations. The results showed that compounds with oxygen-containing pnictogen groups are the best choice for ilmenite beneficiation. The study also explained the chemical bonding mechanism between collectors and ilmenite.

Novel insights into the role of colloidal calcium dioleate in the flotation of calcium minerals

Wenjuan Sun et al.

Summary: This study demonstrated the importance of calcium dioleate formed in oleic acid systems on the flotation of fluorite, calcite, and scheelite, as well as its impact on the adsorption mechanism on mineral surfaces. Calcium dioleate showed better flotation effect on fluorite and scheelite compared to calcite, and it enhanced the surface roughness of these minerals, thereby improving their flotation performance.

Slow-release of fluorite and its effect on flotation separation of magnesite from calcite

Ruolin Wang et al.

Summary: This study found that the application of surface transformation and Pb-BHA collectors can efficiently separate magnesite and calcite. The slow release and surface transformation of fluorite particles play an important role in controlling the flotation of calcite and magnesite.

Al-caustic starch coordination compounds: A new depressant for fine calcite

Ruolin Wang et al.

Summary: The study achieved efficient flotation separation of scheelite from fine calcite by preparing aluminum-caustic starch. Aluminum-caustic starch showed high depressant effect and selectively changed the surface charge of fine calcite. It reacted with the anion of CO(3)(2-) on the surface of fine calcite, instead of reacting with the cation of Ca2+.

Flotation of Fine Particles: A Review

Saeed Farrokhpay et al.

Summary: Flotation of fine particles poses challenges due to their large surface area and low collision efficiency with bubbles. Strategies to address this issue include increasing particle size, reducing bubble size, and utilizing reactor-separator type flotation cells for stronger particle-bubble interaction. The paper discusses the advantages and disadvantages of these strategies.

Effects of Hydration on the Adsorption of Benzohydroxamic Acid on the Lead-Ion-Activated Cassiterite Surface: A DFT Study

Jianyong He et al.

Summary: This study investigates the effects of hydration on the adsorption of benzohydroxamic acid (BHA) onto the oxide mineral surface before and after lead-ion activation through first-principles calculations. The results show that BHA adsorption onto the lead-ion-activated surface is favorable in both thermodynamics and kinetics.

Selective adsorption mechanism of dodecylamine on the hydrated surface of hematite and quartz

Hongliang Zhang et al.

Summary: This study systematically investigated the selective adsorption behaviors of dodecylamine (DDA) and causticized cassava starch (CCS) on the hydrated surface of quartz and hematite through experimental and computational methods. The results showed that increasing DDA dosage can improve TFE grade but reduce concentrate recovery, while increasing CCS dosage can improve concentrate recovery but reduce TFE grade to some extent. The work sheds new light on the selective adsorption mechanism of flotation reagents on the hydrated surface of oxide minerals.

Fluorite particles as a novel barite depressant in terms of surface transformation

Ruolin Wang et al.

Summary: The flotation separation of scheelite and barite is challenging due to their similar chemical properties, but an effective separation can be achieved through the dissolution and surface transformation of fluorite. Fluorite ions play a crucial role in the separation process, affecting the surface charge of barite significantly. Surface transformation is essential for successful flotation and offers a new strategy for separating salt minerals.
