Effects of grinding media on flotation performance of calcite
Mar 01, 2019· Large calcite crystals were ground with steel and ceramic media in parallel in a L ceramic pot using a roller ball mill with grinding concentrate 50% and media filling rate 50%. The grinding products were dried in a vacuum oven below 35 °C and sieved to collect particles with size of −74 + 38 μm for single mineral flotation tests.
