Stardex® 2155 – Mining Dextrin

The Challenge

Sulphide ore flotation plants need selective mineral separation, stable froth, and eco-friendly reagents to boost recovery while meeting stricter environmental norms.

Premier Starch’s Solution

Stardex® 2155 – Mining is a high-purity tapioca-based dextrin acting as a selective depressant in froth flotation of copper, lead, zinc, and other sulphide ores.

Key Benefits

  • Improves flotation selectivity and concentrate grade
  • Enhances froth stability and process control
  • Excellent compatibility with collectors, frothers, and other reagents
  • Renewable, biodegradable alternative to synthetic depressants
  • Custom grades available for specific ore mineralogy

Result

Higher recovery rates with lower environmental footprint.
