Abstract. This study evaluates the environmental profile of ceramic tiles produced in Portugal based on a cradle-to-grave Life Cycle Assessment (LCA), including mining, manufacturing, construction, use and final disposal. The main hotspots are identified and improvement actions are suggested in order to reduce the environmental impacts.
Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to societies, but it may also …
For dolomite, as the H 2 SO 4 concentration increased in a single NaOL collector system, the recovery of dolomite decreased to around 60%. At lower concentrations of NaOL with NP-10 mixed collector, the H 2 SO 4 concentration had minimal impact on the recovery of dolomite, which remained above 85%.

Dolomite is a variation of limestone containing less than fifty percent carbonate. Geologically, dolomite can be formed because of a primary or secondary process. Secondary dolomite occurs because of the process of dolomitization, which is the process of converting calcite minerals into dolomite. Besides, dolomite can also be formed
How to Use Dolomite Lime. Incorporating dolomite lime into your gardening practice is simple: Soil Amendment: Apply dolomite lime to the garden soil at a rate of 2-5 pounds per 100 square feet, depending on the initial soil pH and the desired adjustment.It's best applied in the fall to allow time for the lime to react with the soil before the next …
