Comets are made of frozen gasses and bits of rock and dust. The solid part of most comets can be up to 10 miles across. As a comet gets close to the sun, the heat causes the comet’s frozen gasses to turn into a cloud of vapor and dust. The cloud can be thousands of miles across. Solar winds cause this vapor cloud to trail out behind the comet

Rock Dust CO2 Removal. Nature Journal reports that the removal of atmospheric CO 2 by rock weath ering holds promise for mitigating climate change. Large-scale removal of carbon dioxide from the atmosphere might be achieved through enhanced rock weathering. It now seems that this approach is as promising as other strategies, in terms of cost

Abstract. Rock quarry dust or quarry dust is produced as solid wastes during crushing of rocks to obtain aggregates. This waste product is left in huge heaps in the neighborhood of the quarry causing serious space problems and health hazards. Further, this waste disposal is another problem faced by the industry.

Rock may also need to be specifically placed to control dust generation, the generation of acidic or otherwise potentially toxic water runoff, or seepage to groundwater.Other criteria are required to separate potentially problematic rock, and a carefully considered plan to manage it must be prepared and implemented (eg, INAP, 2014).Historically, with poor quality water from early uranium mines

Rock dust increased the pH to 6.8, but the conditions of the experimental setup reduced the pH of the control to 4.8, way below the ideal pH for tomatoes. Ca and Mg levels did go up with rock dust, but iron and manganese went down – but the study failed to apply statistics to these numbers wo we really don’t know if this is true.

The ETS requires mine operators to increase the incombustible content of combined coal dust, rock dust, and other dust to at least 80 percent in underground areas of bituminous coal mines. The ETS further requires that the incombustible content of such combined dust be raised 0.4 percent for each 0.1 percent of methane present.
