Gallium is a side product of producing aluminum and zinc. Most processing of gallium-bearing raw materials for aluminum and zinc production does not currently incorporate any gallium separation stages. Current rates of gallium production can increase 5-fold without increasing rates of aluminum/zinc production or improving extraction techniques; current extraction techniques would just need to be deployed more widely.
