Once a refinery is placed, the player can place a corresponding extractor for free on any catalyst field. Each refinery can support only one extractor; if the refinery has no connected extractor then it receives no income. Once both the refinery and extractor are complete, the refinery automatically sends harvesters to extract catalyst from the extractor.
See the Refinery article for details on resource collection.
