The famous prize X-prize was created to encourage small aerospace companies to develop a reusable spacecraft of low cost. There is something similar in the field of chemistry?

It would seem so.

The company Barrick Gold has a site in Argentina with a high content of silver, the same this apparently enclosed in a waterproof layer of silica that makes the extraction by conventional methods.
The reduction of particle tamañ0 would be helpful but is energetically costly because the mineral is very hard and abrasive.

Therefore seeking proposals for technologies for more effective extraction and offer a prize of 10 million dollars.

It should be noted that the extraction of precious metals is subject to environmental and social problems , so the technology to operate separate proposal should have a good performance in terms of safety, pollution control, etc.
