Process to protect and beautify the final product. Not all finishes are appropriate for all materials. Some finishes may damage the material or won't stick to the materials. Examples: paint, stain, plating
To solve the process imbalance problem, a layout rearrangement that involves the switching of the first and second ball mills in the process was proposed. The final product was finer, with the 50% passing size reducing from 35 μ m to 31 μ m. The throughput of the industrial plant can therefore be increased by approximately 36% to 8 t/h.

then you would be subject to the requirements. In other words, if conflict minerals end up in your final product – or are necessary in an intermediate process (such as a chemical reaction) – then the law applies. Is my company subject to the law if I only sell products that contain conflict minerals but are made by other companies? Possibly.
