Disclosed is a method for the reduction of mercury emissions from an industrial plant utilizing a cement or minerals kiln that has a high level of mercury. The invention allows for the repeated treatment of a gas stream to reduce the level of mercury and other pollutants through reduction steps, allowing targeted treatment of specific compounds. The invention utilizes multiple sorbent injections for the step-wise reduction in pollutants. Utilizing the multiple stages of reaction, very high levels of mercury emissions may be controlled to greater reduction percentages than existing methods.
