Development of Marine Fertilizer for Effective Utilization of Nitrogen Components in Precious Metal Smelting By-products

Abstract

In order to effectively utilize the nitrogen component of precious metal smelting by-products, nitrate was separated and used for developing solid fertilizer. The solid fertilizer contained in plastic hollow rods with pores of appropriate component elution and persistence investigated in advance was installed above nori (seaweed) growing net. As a result, it was confirmed that the color tone of nori laver was improved in 4 days, indicating the solid fertilizer was effective.
