The Silicon Extractor can be used by a trained operative to mine silicon ore. Silicon can then be further used, after collection, in the Electronics Fabricator. The extractor uses an industrial robot, the silicon dozer, which may become damaged by enemy weapons or harmful creatures and vegetation. In this case it will need to be repaired by someone manning the Engineering Repair Facility. If the silicon dozer becomes too damaged, it will be destroyed and the whole facility will be rendered inoperable. A replacement silicon dozer can be manufactured, however, in an Industrial Robotics Factory if provided enough iron and electronics.
