Silver from Galena Extraction
After reading a forum post from user Udary titled 'A use for Galena', he mentions a way to extract silver from the currently unused ore Galena. As I had never developed a mod before and I love playing TFC, I thought it a good idea to try a create a mod outlining the process Udary mentioned.

After a little research on the subject I have created a mod that allows the user to extract Silver from Galena.

The process is expensive in terms of the amount of silver returned from the Galena ore, but I did not want this extraction process to become the main source of silver. It was designed as a stop gap until a more viable source of Silver was found. Some ores are not used until later stages of TFC and I will be the first to admit that after investing a lot of time in a world, only to find some ores impossible to find can be frustrating.

Nickel from Limonite Extraction
In my current world I was unable to find two ores, Silver and Garnierite. I had already solved the problem of Silver, so now I needed a way to get Nickel. After a little research, I found that Nickel is present in Limonite. So working on a similar method as the Galena Extraction, I created a Nickel from Limonite extraction process.

Again this process is expensive in terms of the amount of nickel returned from the Limonite ore. This was not designed to replace the main ore mining, but provide a way to get small amounts of nickel to move forward.
