Nickel sulphate Crystals Disposal

Our client has accumulated many thousands of pounds of nickel sulphate crystal materials. We are required by environmental regulations to dispose or recycle. Is there a method of redissolving with subsequent plating out? Or do we just have to haul it away.

What you want to do is find a recycler for this material, which will relieve you of further responsibility; because of the nickel value; this will cost less than landfilling, maybe even nothing.

You need to be very careful, and on the right side of the regulators, before attempting redissolution and plating out. Some people will consider this as operating a recycling/recovery facility rather than a plating wastewater treatment operation, and it can cause unlimited grief if they decide to harass your client over it.
