can gold dust escape this kind of incineration?

[diverwild]

this is 18K polishing bags I used to incinerate them from below with out flame، then I found that giving it a spark from above will burn it quickly and eat the horrible smoke that fills all the garden ، but I thought this fire may let some gold dust fly by what do you think

Cover it with a screen. I use one meant to cover a hot skillet. It isn't perfect, but better than nothing.

I have no idea what a polishing bag is but, if it's similar to jeweler's buffing dust, you will definitely lose gold during the incineration under the conditions i see in the photo. Incinerated buffing dust is the dustiest material I have ever seen when it is disturbed in the very least. Buffing dust should never be incinerated in the open air. The loses can be considerable.
