What do you mean by "ton"? When recovering precious metals from electronics (and anything else), yeild is everything. Plating is measured in microinches, so volume is very important. Also, your images show a variety of materials that would require different recovery techniques, so, once again, volume of each type of material is very important.

Galenrog I am aware of that I have about 36 sets of these boards. So 6x36 Boards and I will be getting more. However I have done the acid process before for fingers and boards but how would you recommend doing the other pieces. Also why is is so important to keep the solder out. Also I have some that are silver are they worth recovering

Since I have no idea what your level of expertise is, I will first send you to where I send anyone else that wants to learn. First stop is goldrefiningforum.com. Particularly the sections on safety and wastes. The section called The Library is probably the most useful for procedures, since it is made up of the most useful past threads with much of the fluff edited out.

Next, I suggest a copy of "Refining Precious Metal Wastes" by C M Hoke. While originally published in 1940, many of the techniques are fully applicable to much of the electronic waste you are working with.

Stay away from YouTube. While there are many good recovery and refining videos, the number of videos that could easily get someone hurt or killed are far more numerous.
