Thionocarbamate Storage — Aero Z-200 IPETC Tank Selection for Selective Copper Flotation

Storing Thionocarbamates? Start Here

If you're dealing with thionocarbamates, you're likely in the mining industry, using them for their excellent ability to selectively collect copper sulfide minerals while leaving pyrite behind. They come in liquid form, often in drums or totes, and are known for being safer to handle than some alternatives like xanthates. But how do you store them safely and effectively? Let's break it down.

Can you store it in a poly tank?

Yes, you can store thionocarbamates in polyethylene tanks. Both HDPE and XLPE tanks are suitable for this purpose, especially if they are opaque to reduce light exposure. Polypropylene fittings and Viton gaskets are recommended for neat liquids, while EPDM gaskets work well for emulsions. Avoid carbon steel and copper alloys as they can react negatively with thionocarbamates.

Key Issue: Material Compatibility

When storing thionocarbamates, material compatibility is crucial. These chemicals can react with certain metals, so it's important to use materials that can handle mild alkalinity and low-level sulfur vapors. Always ensure that your storage setup eliminates contact with strong acids to prevent unwanted reactions.

The safety that actually matters

• Use opaque HDPE tanks to minimize light exposure.
• Ensure all fittings and gaskets are made from compatible materials like polypropylene and Viton.
• Avoid any contact with carbon steel or copper alloys.
• Maintain proper ventilation to handle any sulfur vapors.
• Follow all relevant safety regulations and guidelines.

Common questions

Can thionocarbamates be stored in stainless steel tanks?

Yes, 316L stainless steel is suitable for premium installations, especially in hot climates.

What should I do if I detect a sulfur smell?

Ensure proper ventilation and check for any leaks or material incompatibility in your storage system.

Are thionocarbamates safe for transport?

Yes, they are generally non-regulated for transport, but always check the specific guidelines applicable to your region.
