Thionocarbamate (Z-200 IPETC) Collector Storage — Selective Copper Sulfide Flotation Tank Selection

Storing Thionocarbamate Collector? Start Here

Thionocarbamate collectors, like Z-200, are essential in copper-sulfide mining for their ability to selectively recover copper minerals while minimizing pyrite. This yellow to brown oily liquid is used directly in flotation processes, making it a staple in copper, copper-molybdenum, and copper-gold concentrators. Whether you're managing a mining operation or handling chemical storage, understanding the right way to store this collector is crucial for maintaining its effectiveness and safety.

Can you store it in a poly tank?

Yes, you can store thionocarbamate collectors like Z-200 in polyethylene tanks. HDPE or XLPE tanks are standard for this purpose, as they are compatible with the chemical's mildly acidic to neutral nature and specific gravity. Ensure the tanks are UV-stabilized for outdoor use.

Key Issue: Cold Weather Viscosity

In cold climates, the viscosity of thionocarbamate collectors increases significantly. This can affect the flow and dosing of the chemical. To prevent issues, use heat-tracing on tanks and piping to maintain optimal flow conditions.

The safety that actually matters

• Use UV-stabilized tanks for outdoor storage to prevent degradation.
• Apply heat-tracing in cold environments to maintain fluidity.
• Ensure proper gasket selection, typically EPDM, for leak prevention.

Common questions

Can thionocarbamate collectors be stored in stainless steel tanks?

Yes, both 304L and 316L stainless steel are suitable for premium installations.

What type of gaskets should be used?

EPDM gaskets are standard, but consult the manufacturer's chart for specific applications.

Is thionocarbamate safe for copper piping?

No, avoid using copper or brass as they can corrode when in contact with thionocarbamate.
