YOU came HERE because YOU WANTED information. That was perhaps one of the wisest decisions you could have made. Almost, without exception, every question you have right now or are likely to come up with in the future has already been asked (and answered) by someone here. Most times, the questions have been asked many times over. THE SEARCH ENGINES ARE YOUR FRIENDS. Use them.
Before you start to ask questions, read the 4 announcements posted by Harold_V. I believe they are at the top of EVERY forum section (but I could be wrong on that). Harold is one (if not THE) premier mentor on this site. Pretty much what he says, goes. Harold is a person who speaks what is on his mind. He is direct and there is a lot he will not tolerate. LISTEN to him. He has the respect of EVERYONE on this forum. You can disagree with anyone on the forum. But I caution you, do it with respect, or you will be banned.
Dealing with Precious Metals (PM's) is usually a two step process involving Recovery and Refining (R&R). It makes no sense to recover a hundred pounds of gold, only to find it is 10% pure (or even less). It then needs to be refined. By following the advice given, you can ensure your gold will be of high quality and something you will be proud to own and share with your friends and family. The very best advice anyone can offer is to put your precious metal bearing materials away and start reading. As you read, keep collecting your materials which contain precious metals. Also, start to collect the other items you will need for your plunge into R&R. Remember, your PM's will be right where you left them until you start to process them. If you use the wrong process, or don't follow the correct steps, you will most likely lose PM's or make their recovery much more difficult. Most of us here have made mistakes and speak from experience. It is much easier, faster, and safer not to make the mistakes to begin with.
What you are asking entails a ton of information. It is not unlike asking "How do I fly a helicopter?". Most of the members on the forum have regular jobs to attend, so answering posts where the questions have been asked numerous times just WILL NOT HAPPEN. No one will not spoon feed you the answers. If you WANT the information bad enough, you must show a willingness to put forth the effort to study. After you have studied, you will, on occasion, have a question which you have not seen addressed, or simply cannot understand the concept. The senior forum members (you will soon find out who they are by studying their posts) have, literally hundreds of years of experience dealing with almost every aspect of precious metals. Many have wide ranging experience on different methods, and some have a less broad range, but have detailed experience in particular areas. They are all experts. There is more FREE information here than you could likely get at any single University.
Many members have their own websites with free videos you can watch. In addition to the videos, Lasersteve has many of the items you will need for sale. His prices are very reasonable and he ships things quickly. He is not going to get rich from the items he sells, but he has found sources for some things that may not be easy to find elsewhere. Samuel-a has a website and Patnor1011 sells some items via eBay.
There is also a lot here that is worth more than all the PM's you will ever encounter. It deals with the hazards you are likely to encounter and how to deal with them safely and responsibly. Do not throw anything away until you are certain it no longer contains PM's, and that it is safe for the environment. DO NOT WORK INDOORS, unless you have a proper fume hood. With the chemicals you will be using, you could easily kill yourself, your family, friends, neighbors, and pets. There is no amount of PM's worth losing your life over. Sodium Hydroxide (lye) will cause almost instant blindness if it gets into your eyes. Use the proper safety gear as recommended by the process you will be using.
