I am aware of the basic principle and the process of Aqua Regia.

Welcome.
First of all you are starting in the wrong end.
To start a refinery you need all the permits in order.
This will require at least a business permit.
When these permits are secured (waste permits, discharge permits and so on), you need to aquire the equipment to process wht ever you are processing.
Then you should already have the permits to buy the chemicals you need.
Next we really do not use Urea, we use Sulfamic acid or better use the "correct" amount of Nitric.
For Gold refining there is no need for Sodium Hydroxide, nor Zinc powder.
Better get som Copper powder.
Stannous are made on site by Tin and HCl.

What is filter powder?

Why type material are you going to run? EWaste, karat gold, ores? It could help to narrow down what would work best for your situation.
