The problem of utilization of by-products in diamond mining at the “Severalmaz” concentration factory

Abstract

The problem of using saponite containing tailings obtained as a by-product in the territory of the M. V. Lomonosov diamond Deposit (“Severalmaz”) not only for technical purposes, but also as an ameliorant and mineral fertilizer in agricultural production is considered. The results of vegetation field experiments on row crops and in the closed ground when growing arugula and lettuce are shown. The experience of 2017 was laid in atypical weather conditions, but the data show a positive impact of different doses of saponite on soil, crop and potato quality. The experience of 2018 in the conditions of hothouse facilities with leaf vegetables also confirms the influence of introduction of saponite in the soil on the content of nitrates in production.
