Ready-made effective formulas for the use of polymers practically do not exist

One ask me: "Can you create a formula for using polymers in the flotation for my ore?"

I answered: "I can create a formula. Ready-made effective formulas practically do not exist. Experts are needed to create complex formulas for the use of polymers for each particular ore.

I found that the mechanism of action and the intended effect depends on:

• Type of polymers.
• Dosage of polymers.
• Order of addition of polymers.
• Method of polymer preparation.
• Independent use or as a mixture with collectors.
• Conditioning time of the polymer with the pulp.
• Time of polymer decomposition
• Polymer addition points.
• Type of minerals.
• Particle size of minerals.
• Presence in the mineral of fine, ultrafine particles, clays.
• Water hardness.
• Type of machinery.
• Circuit configuration and circulating load.

If used improperly, polymers can suppress all minerals!

The most known naturally polymers are:
Carboxymethyl cellulose (CMC)
Starch (Amylum)
Dextrin
Guar gum (Guaran)"
