As I said that is all you need to make a big mess.
You seen a video and read a little, the video is done by someone who has studied for years, and is showing a very small portion of a process or processes (I am unsure of the video you are referring to and cannot comment on it specifically), what you will not see or learn from watching a video is the information and knowledge you will need to go from scrap to gold and deal with waste...
The video would have to be longer than most CD's could store data, to teach you all of the things you will need to learn, and understand.
The video would be a great help to someone who already understood all of the processes and the basics of recovery and refining, but for not a beginner with little understanding of the chemistry, dangers, and so on, especially if having to ask what chemicals he would need (I do not see anything in your list to treat waste, what I do see is some chemical in your list that could form an explosive mix with metals in solution if not used properly.
I am not trying to give you a hard time, I am actually trying to help you get started.
Right now (as far as I know) you do not need any chemicals, you can get what you need when you know you need it (I could give you a very large list of chemical we use, but if you ran out and bought them what would you do with them, until you knew you had a use?
What you need is to get a basic understanding and knowledge of recovery and refining, understand the safety involved, know how to deal with waste, know how to keep yourself and others safe from corrosive acids, poisonous gases, and deadly toxic waste, understand how metals react with chemicals, and how metals can form explosive mixes...
Basically you need to put the horse in front of the cart if you wish to get anywhere, right now you have the cart in front of the horse and trying to go backwards to learn, this is a recipe for a big mess and disaster and much frustration on your part.
Work on the process in the video after you get the basic understanding and then you will do much better.
Start with hokes book, concentrate on it, read it through once, then go back an read again the getting acquainted experiments, now you will know what chemicals you need to do these small experiments, observing the reactions will give you an understanding words or videos cannot, study the forum the safety section and dealing with waste, study the processes that interest you learn all you can about them, basically get a good understanding and knowledge of what you need and why, get a good grasp on the chemistry, and the safety.
Learn to recover gold and precious metals and refine them to high purity, not starting out trying things you understand very little about making big dangerous messes and standing there with a look of confusion, wondering where your gold went and what to do next.
This chemistry of metals is a complicated science, treat it as such, study and work as a chemist gaining an understanding by study small experiments and increasing your knowledge know what needs to be done before you do it, have a good idea of what to expect, and if things do not go as suspected (many times they will not), know why and what to do.
Forget about getting gold for the time being,(that will come in due time as you gain knowledge, understanding, and skill) work on gaining understanding knowledge and skill, then the gold will come easy, you will know how to handle it and any problem that comes your way, put your horse before the cart and you will go far, jumping in before will be a big mess.
just trying to help.
I look forward to you becoming a skilled workman in this art, it will take time to learn, but I will enjoy watching you grow, and look forward to seeing you help others learn from what you are learning, and if you work hard I bet you will be teaching me a few tricks.
Welcome to the forum. I am just trying to help you get started on the best path.
