The invention discloses a heterogenite leaching method with low cost. The heterogenite leaching method comprises the following steps that (1), heterogenite is added into a reactive tank, and water andconcentrated sulfuric acid mixture mixing are added according to the predetermined liquid-solid ratio and acidity; (2), Cu-Co-Fe alloy is added into the material after mixing obtained in the step (1), air is introduced to assist in stirring to leach, the leaching temperature and stirring speed are controlled to achieve predetermined leaching time; and (3), the slurry after reaction in the step (2) is subjected to solid-liquid separation, and a leaching agent and leaching residues are obtained. The heterogenite leaching method with low cost has the characteristics of low energy consumption, low cost and low pollution. 本发明公开了种低成本的水钴矿浸出方法，包括以下步骤：（1）将水钴矿加入反应槽，并按照预定液固比和酸度加入水和浓硫酸混合调浆；（2)将铜钴铁合金加入到步骤（1）所得调浆后料中，并通入空气辅助搅拌浸出，控制浸出温度和搅拌速度达到预定浸出时间即可；（3）将步骤（2）反应完后的料浆进行固液分离，得到浸出液和浸出渣。本发明的低成本的水钴矿浸出方法具有低能耗、低成本和低污染的特点。
