There is only one company listed, as a supplier of proppants in New Jersey, and that company is Asbury Graphite Mills. However, many companies already established in the state, such as Santrol, Promex Ceramics, and US Silica are suppliers of such products. I would believe, since there is a market for silica proppants, that sand from the state is already being shipped across our borders. I am aware of the fact that the article is focusing on the sale of A&H, but there isn't any difference if sand is removed for filtration, construction, or proppants. Mining is mining. I would pay attention more to how the sands are labeled. The word fracking now has some negative meaning behind it. Proppant silica, resin coated sand, and whole grain quartz proppant sound much better to the general public, even though they mean the same as fracking sand.
