Learning gold recovery and refining (a very complicated art and science, that involves understanding and skills), would be like learning electronics.
You will not have much luck building a good working stereo radio from a pile of scrap electronic parts without studying to learn the science and art of electronics, working and studying to get the education needed, to understand How a radio works, and how to build one, and how to improve your skills.
Study can be work, but if it is something you are interested in, and truly wish to learn, and you like discovering very valuable useful information, then study is no longer work (or a bad word), but a fun and enjoyable means to an end, to get gold and make it pure in your melting dish.
School can make study a bad word.
I do not go to school to learn recovery and refining, I come to the forum and Hokes book, and dig through a very rich gold mine of available information, to learn and improve my skills at getting gold, and melting it as pure as possible.
I search and dig through the gold mine of useful information to find those precious nuggets of information, I can use to get that gold and to make it pure gold in my melting dish.
So in a way, I am mining for my education, to get that gold.
So I can consider reading the forum and Hoke's book as mining for information on gold, to get gold.
Anyway you look at it, to get gold you will have to do a lot of work, but if you love the work it becomes fun. Enjoy mining and you barely feel the pains, and seeing that gold in your pan, you will feel no pain as you jump for joy.
Along with this study you have to learn to improve the skills you learn through study and practice.
I do not understand a person who thinks they could learn such a complicated field of work without putting in the effort needed to get the needed that valuable education, and to learn the skills needed, they think gold and the recovery and refining of it, is an easy matter. If they refuse to put out that effort not only will they miss out in an opportunity of learning where to find more of the gold, and how to recover it, and how to refine it.
They would actually be losing gold trying it without an education,or gaining the skills needed through that education.
And with the chemistry involved here they risk their safety and the safety of others, they think they can watch a couple of videos, ask a few questions, or see some one do it and learn that way.
I could watch a pilot fly a jet, but I would not learn to fly that jet that way, I would have to do some study learning to fly the jet, I doubt the pilot could teach me to fly the jet by answering a few of my questions, and if I jump into that jet before I learned to fly, I will most likely hurt myself and others and lose that jet plane in a crash.
If you wish to get gold you will have to work.
Mine for your gold Hoke's book is a great place to begin.
