Butyl Diglyme Drops Contents on Wash Step

[MotoLupe]

I am having trouble with Butyl Diglyme dropping contents on wash cycle. I use HCL-CL method on gold ore and Butyl Diglyme will pick up yellow material and will pick up multiple shots of material but dumps it on the first wash.

You're washing it with what and how does it precipitate ? Can you include a pic ?
