A novel system for chemically leaching ore that decreases pollution to the environment and that enhances reaction kinetics and economic considerations. An impervious covering (18) blankets a distribution network of drip lines (17) laid over the ore heap (14). A lixiviate containing solution is forced by means of a pump (11) through a venturi eductor (19) into the distribution network of drip lines (17) for application to the ore heap (14). After percolating through the ore heap (14), the leach solution is recycled through a recovery system (16) to the venturi eductor (19).
