Dual-reagent system
HB-1 and HB-2 can be used alone or in blends according to ore properties, depressant scheme and plant objectives, forming recovery-priority and enrichment-priority windows.
Scheelite Flotation System
An industrial window for scheelite recovery and enrichment
HB-1 and HB-2 scheelite flotation reagents are designed for low-grade tungsten roughing, scavenging and low-temperature pulp conditions, bringing rougher recovery, enrichment ratio and collector dosage into one adjustable plant-oriented system.
Product Logic
A plant-ready selectivity window, not only stronger flotation
Scheelite ores often combine low feed grade, close gangue response and a difficult trade-off between rougher recovery and enrichment ratio. Hebe uses HB-1/HB-2 as a single-reagent or blendable collector system evaluated together with the plant depressant scheme.
Low-dosage response
Plant-pulp verification showed meaningful rougher response and high enrichment in the 120-180 g/t collector dosage range.
Plant evaluation
WO3 recovery, rougher concentrate grade, enrichment ratio, froth condition and depressant synergy are evaluated together.
