Granular soil prepared from ferronickel slag

Abstract

The invention relates to the field of planting matrixes, in particular to granular soil prepared from ferronickel slag. Aiming at the problem of low utilization rate of ferronickel slag, the inventionprovides granular soil which is prepared from ferronickel slag and has a porous structure. The granular soil is spherical particles with the porosity of 55-70%; the ferronickel slag porous brick is prepared from the following raw materials in parts by weight: 100 parts of ferronickel slag fine powder, 0-35 parts of a pore-forming agent, 2-20 parts of a plasticizer, 0-3 parts of a pigment, 0.2-1.5parts of a water reducing agent and 10-35 parts of a pH adjusting solution. According to the invention, ferronickel slag fine powder is used as a main raw material; the ferronickel slag is rich in silicon oxide and magnesium oxide components; certain pores and strength are realized after high-temperature sintering; meanwhile, metal ions such as nickel and iron in the ferronickel slag can store alarge amount of water after forming hydrated metal ions with water, and the hydrated metal ions are not easy to evaporate, so that the pollution problem can be effectively relieved, and the prepared granular soil has good water, fertilizer and air permeability and is beneficial to plant growth.

AI Technical Summary

Benefits of technology

This patented method involves preparation of small particles called ferrous acid (Fe2O3) or metallic iron). These tiny particles are made from finely ground flake containing these elements like zinc but without any impurities such as sulfur dioxides. They have many benefits when applied on various types of crops including plants' roots, root systems, nutrients, moisture content, etc., making them ideal for agricultural purposes. Additionally, they provide excellent properties during storage at room temperatures over long periods of time due to their strong hydrophobicity and ability to absorb liquids easily.

Problems solved by technology

The technical problem addressed in this patents relates to efficiently recovering waste from pyroelectric acidic liquid that occurs when producing iron alloys at an industrial level. This material includes various types of metal sulfides (such as FeS) along with some impurities like manganese). These compounds have poor solubility properties making it difficult to separate these components effectively without causing environmental concerns. Additionally, there may exist methods for preparing different forms of granules containing specific ingredients useful in agricultural applications.
