CONCENTRATION PLANT

Concentration plant - this building allows your character to refine the resources into a concentrated form.
In this form the weight of the resource is significantly reduced. City officials set which types of resources can be refined and refinement cost (per unit).

To enrich the resources press the "Refine" button and deposit the resources from your backpack into the plant's storeroom. Then press the "Start" button to go on to the next step.
The total cost of enrichment will be automatically calculated for you at this point. If you are satisfied with the price, press "Yes" and the enrichment process will start. By pressing the "No" button you will cancel all previous actions.
After the process is complete the enriched resources are moved to your backpack. At this point their weight has been halved.
