Excerpts from study:

“Abstract

Due to the influence of the clay minerals, the grade of the concentrate from a gold concentrator in Northwest China is low, which significantly compromises product valuation and market competitivenes. This study evaluated the industrial potential of fenugreek polysaccharide gum (FGM) as a depressant to enhance the flotation through pilot-scale testing. Results showed that the FGM system effectively upgraded the concentrate grade by 4.7 g/t, while slightly increasing recovery by 0.37%. The application of FGM has generated an additional $1.715 million profit over the past two years. These findings suggest that FGM holds significant potential for large-scale industrialization in the flotation of high-clay-content sulfide ores.”

Study: Promising Fenugreek Gum Polymer: Adjuvants for Drone-Based Aerial Chemical Applications to Mitigate Off-Target Drift

“We sprayed water (control), fenugreek polymer (FP) suspension (FP is a nontoxic food-grade polysaccharide derived from the seeds of fenugreek (Trigonella foenum-graecum L.), a legume (Fabaceae) grown in North Africa and Asia), insecticides imidacloprid, and bifenthrin as different treatments. Bee visitation results for fenugreek solution were similar to water and significantly higher than insecticide-alone treatments (unpublished).”

Influence of Fenugreek Gum and Particle Size on Performance of Talc Flotation

In this work, the effect of fenugreek-gum (FG) on the depression of talc with different particle sizes and the depression mechanism were systematically investigated. The floatability of talc was influenced by the granularity, and the floatability of talc in different particle sizes followed the order: -0.074+0.037mm > -0.037mm > -0.010mm. FG had a strong depressing effect on talc, especially for coarse talc, the -0.074+0.037mm size fraction of talc was completely depressed by 2.5 mg/ dm3 FG. The depressing effect of FG for talc was influenced by particle size. Larger dosage of FG was needed in order to completely depress talc with smaller particle size. The absolute value of talc surface charge and the inter-particle repulsion decreased in the presence of FG, causing easier inter-particle flocculation. FG interacted with talc surface by chemical adsorption.

Fenugreek Gum: Depressant Galactomannan Study

Fenugreek Gum: Depressant Galactomannan Study

The effect of the depressant galactomannan or fenugreek powder gum indicates that the flotation results show fenugreek gum had a straining influence on the depression of talc while had little effect on nickel minerals flotation. Compared with the depressant carboxymethyl cellulose (CMC) and guar gum, the fenugreek gum increased the nickel recovery dramatically, it not only negated the need for a talc removal process but also achieved a significant decrease in the depressant consumption by half. Zeta-potential and infrared spectrum measurements illustrated that chemical adsorption was seen between KGM and talc, and a possible weak physical adsorption was seen between KGM and pentlandite. This was the reason why KGM had high depression selectivity for talc and little depression effect on nickel minerals.

Investigational Studies on Highly Purified Fenugreek Gum as Emulsifying Agent

In this study, highly purified galactomannan containing fenugreek gum was isolated by newly reported method and investigated for its surface and emulsification property. Comparative studies were carried out with other galactomannan containing natural emulsifiers like locust bean gum, guar gum, and non-galactomannan anionic xanthan gum. The results revealed that highly purified fenugreek gum has better surface and interfacial tension reducing property among all gums used in this study. Emulsion prepared with 0.6% highly purified fenugreek gum showed greater reduction in droplets size with greater surface area compared to guar gum, locust bean gum, and xanthan gum emulsion. Zeta potential values indicated that highly purified fenugreek gum emulsion showed greater repulsive forces and was able to form more stable emulsion compared to other gums. No coalescence or phase separation was observed during storage.
