Ore to Refined Metals, Am I Missing Something? : X4Foundations

In the encyclopedia it says it takes 240 Ore to make 1 Refined Metal. So a ratio of 240:1. So if my math works out correctly it takes 12,000CR of Ore to make 150CR of Refined Metals, resulting in a loss of 11,850CR. If it was somewhere between a 1:1 conversion ratio or 2.5:1 then the economics could work out better with slight profits for refining.
