The invention discloses a thiosulfate gold extraction method taking an alkyl trimethyl quaternary ammonium salt as an additive and belongs to the technical field of wet metallurgy. Aiming at the problems of a traditional thiosulfate leaching method adopted by some ores that the leaching efficiency is low and the consumption of reagents is great, ore pulp is modified and then is treated; after the ore pulp is modified by using the thiosulfate gold extraction method, thiosulfate, ethidene diamine and a copper ion gold leaching solution are used for leaching and the leaching rate is higher than 75%; the process is simple to operate and easy to control; the consumption amount of the thiosulfate is very low; components of the gold leaching solution are simple and gold in the gold leaching solution is easy to recycle; the applicable range is wide and the leaching effect is good under the condition that the pH (Potential of Hydrogen) is 9-12; the leaching speed of gold ores which are highly slimed by limonite is rapid and the relatively-high gold leaching rate can be kept; toxic substances including sodium cyanide and the like are not utilized in a gold extraction process and toxic wastes are not discharged; the thiosulfate gold extraction method is environment-friendly.

Disclosed herein are methods for otoprotection against platinum-based antineoplastic agents by administering a thiosulfate salt to a subject in need thereof. Typically, the thiosulfate salt is administered to the subject scheduled to be administered a platinum-based antineoplastic agent within 4 hours. Alternatively, the thiosulfate salt is administered within 7 hours after the administration of a platinum-based neoplastic agent.

The invention relates to a coated granular fertilizer, preferably wherein granules are sulfate-based or phosphate-based. When sulfate based granules, as in ammonium sulfate, the coating substance is an inorganic salt of alkaline earth elements, preferably calcium, such that when applied to the surface of fertilizers, forms calcium sulfate, preferably a calcium sulfate-dihydrate, as a protective coating. For a reactive coating of a thiosulfate, free sulfuric acid present on the granule reacts to provide an elemental sulfur coating. For ammonium phosphate-based granules, coatings may comprise compounds of Ca++, Al+++ and / or Fe+++ salts thereby forming a calcium, an aluminum, an iron, or mixed cation phosphate protective coating. Thiosulfate is also effective with phosphate based granules which are manufactured with sulfuric acid. Granules coated according to the disclosure have advantageous properties as the coating can be applied in a specified and sparing manner due to its tendency to adhere to surfaces during the reaction. Coated fertilizer granules of the disclosure are also advantageous in that, with regard to the applied amount of coating, they provide increased resistance to dusting in long term warehouse storage, to moisture uptake and to oxidative heating. Coating components also add nutrients to plants that can provide nutrients over a longer period of time such as a slow-release characteristic.
