DASEN MINING’s Barite ore Flotation Experiments and Results

/in /by

Barite is a white or colorless mineral composed of barium sulfate (BaSO4) and is the main source of elemental barium.

DASEN MINING  received a 40kg sample of barite ore from a client in Morocco, with a specific request: to upgrade the barite to a purity level where BaSO4 exceeds 90% and SiO2 is less than 0.1%.

 

Upon receiving the barite ore sample, our dedicated engineering team at DASEN MINING conducted a thorough analysis of the raw material. The results were as follows:

Barite sample 1: 20kg, 0-2mm, content 74.75%, middlings, specific gravity 3.81.
Purpose of flotation experiment: whether barite with a specific gravity of 4.38-4.40 can be produced.

Barite sample 2: 20kg, 0-2mm, content 55.84%, tailings, specific gravity 3.42.
Purpose of flotation experiment: whether barite with a specific gravity of 4.38-4.40 can be produced.

Other Impurities: Calcium, magnesium, and aluminum were present in varying concentrations, which must be effectively suppressed during the flotation process.

Our team proposed a customized flotation separation flow sheet based on this analysis. This flow sheet was designed to maximize the recovery of barite while minimizing the presence of impurities.

We are currently in the process of conducting further flotation experiments. We have requested additional samples from our client to refine our process and achieve the desired purity levels. Our goal is to fine-tune the flotation reagents and process parameters to effectively suppress the impurities and enhance the recovery of high-purity barite.

At DASEN MINING, we are committed to pushing the boundaries of mineral processing technology. Our journey with the Moroccan barite ore is a testament to our dedication to innovation and excellence. We are confident that with further experimentation and optimization, we will achieve the desired results and unlock the full potential of this valuable mineral.
