Hi, and Welcome to the forum.
As for the gender issues with refining metals, please read C.M Hokes book and check the gender of author.
Please disregard learning from videos, as a lot of these video posters are acid wasters and boil of huge amounts of acid into the air in their area for no reason other than they do not want to change. They purposely sabotage the videos they attempt using other methods, leave out key steps like water needs to be distilled water, not tap water, even ice cubes should be from distilled water as tap waters are containing more and more things.
I ruined my first processing attempt because of the additives in my city's water, turned chalk white and I could never get the gold out of it. Sent the mess to my Guru and not sure He ever got the values out of the mess.
1. Find a material that you are going to work with.( I.E. Gold filled)
2. Figure out the process that seams best to you for processing your chosen material.
3. Set up all the equipment and PPE you will need for this process.
4. Make a procedure flow chart with all steps laid for you to follow.
5. Figure out waste storage and processing for the waste produced from your chosen method.
6. Start small, take notes and come back with clear questions for the issues your writing down in the note book.
