Can the silver contained in zinc ash from steel mills be extracted? Is there anyone knowledgeable who can provide the technology?

As the title suggests, the silver content is approximately 300 grams per ton.
It can be enriched through mineral processing; direct extraction is difficult.
Thank you all for your suggestions. Is there any suitable factory to choose?
With such a high zinc content, recovering silver separately must be costly.

Given such high levels of zinc, recovering silver alone is not a good option; it would be better to first use a rotary kiln volatilization method to extract the zinc, thereby concentrating the silver in the slag, and then proceed with the recovery of silver.
Reply to 7# xavier_xasm: Does the silver contained in this slag still need to be recovered through flotation? Thank you.
