Jales spill line The jales are pulverized rocks after the extraccion of the mineral and are send through lines to "gash of the volcano". I have as a proyect make a new spill line because the first "gash" is full and the company need to have other place to storage. It is a good proyect because i'm learning much about of accesories, mechanical, and a lot of civil engineering thing and the proyect will benefit to the near communities that are affected for the fall into Jales in rainy days.
