ORFOM® D8 DEPRESSANT

• Compatible with typical flotation reagents
• Maintains performance at system pH >7
• Is less odorous and has a lower toxicity profile than other traditional depressants like Sodium Hydrosulfide (NaSH) and NOKES
• Highly effective at significantly lower dosage than NaSH and NOKES
• Does not oxidize in air so does not require use of an expensive inert atmosphere system to maintain product performance
• Offered as a 38% aqueous solution, and used as is, to maximize safety and minimize handling issues associated with alternative reagent preparation
• No reportable shelf-life issues
• SDS reports respiratory protection not required
• TSCA registered and REACH compliant

Advantages in Primary Molybdenum Operations

• Very effective in depressing iron and copper with contribution to depressing lead sulfide minerals when added to the ball mill or cleaner circuit 
• Proven to maximize grade when used with NOKES reagent while minimizing total depressant dosage

Advantages in Copper-Molybdenum Separation Operations

• Effectively depresses copper from copper-molybdenum bulk concentrate
• Proven full replacement depressant to NaSH and other alternative depressant systems
• Achieve stable final molybdenum concentrate grade 
• Reduces total reagent consumption
