Blasting composition and method of making same
First Claim
1. A non-emulsified blasting composition which consists essentially of a substantially uniform mixture of from about 80 to about 94 weight per cent ammonium nitrate, from about 3 to about 6 weight per cent oxidizeable carbonaceous material, from about 0.1 to about 10 weight per cent organic acid soluble in said carbonaceous material and having about 8 to about 20 carbon atoms, from about 1 to about 9 weight per cent water and from about 0.5 to about 1.5 moles of ammonia per mole of said organic acid, and wherein the density of the said blasting composition is greater than the density of water.

Abstract
Improved blasting compositions are prepared by the addition of a solution of an oil-soluble organic acid in fuel oil to prilled ammonium nitrate, followed by the addition of water, in controlled amounts, and ammonia, as an aqueous solution or in gaseous form, and mixing the resultant mixture until the density of the final product exceeds the density of water.

- 13. A process for the preparation of a blasting composition which comprises mixing from about 80 to about 94 per cent ammonium nitrate with from about 0.1 to about 10 weight per cent acid, from about 3 to about 6 weight per cent oxidizeable carbonaceous material, from about 1 to about 9 weight per cent water and from about 0.5 to about 1.5 moles of ammonia per mole of said acid, wherein said acid contains from about 8 to about 20 carbon atoms and is soluble in said oxidizeable carbonaceous material, carrying on the mixing of said components until the resultant product attains a density greater than the density of water.
