0.9.7 Concentrated Tailings for ECO is a free Windows mod designed to enhance gameplay by introducing two new blocks: Concentrated Tailings and Concentrated Wet Tailings. These blocks can be crafted from three respective tailings blocks in the blast furnace, adding depth to resource management within the game. Notably, these new blocks produce three times the amount of ground pollution, presenting players with new challenges in environmental management.

The mod is straightforward to install; users simply need to extract the 'ConcentratedTailings' folder into the 'Mods\UserCode' directory of their server files. While the current version does not include models for the blocks when carried in shovels, this decision was made to optimize file size. Future updates may incorporate these models based on user feedback.
