Sulfur slag sorting process, sulfuric acid slag treatment program, sulfur slag comprehensive utilization solutions

1. Program Overview

This solution for the chemical industry produces sulfur slag (sulfuric acid slag) characteristics, to provide specialized sulfur slag sorting treatment and resource utilization of the overall solution. Sulfur slag is the solid waste produced in the process of sulfuric iron ore acid production, containing rich iron resources and other valuable components. Through the scientific design of sulfur slag treatment process, the iron minerals can be efficiently recovered, and realize the resource utilization of tailings, creating economic and environmental benefits.

2. Characterization of raw materials

Sulfur slag iron element mainly exists in the form of iron oxide, according to the different degrees of sintering can be divided into three categories:

• Peroxide sulfate slag: reddish brown, mainly containing hematite

• Normal sulfuric acid slag: iron black, hematite and magnetite content is equal

• Under-oxygenated sulfuric acid slag: iron black, mainly containing magnetite

Different properties of sulfur slag need to use different separation process, in order to achieve the ideal recovery results.

3. Sulfur slag separation process design

Raw material pretreatment
Sulfur slag raw materials → uniform feed → crushing and screening → particle size classification

10. Sulfur slag treatment program configuration

Program A (metal recovery type)

Focusing on the maximization of iron metal recovery, the investment is relatively concentrated and the return cycle is short. The program adopts the mature gravity separation - magnetic separation joint process, for the sulfur slag in the iron mineral characteristics of efficient recovery, is currently the mainstream sulfur slag treatment.

Recommended reason:

• Fast investment recovery, significant economic benefits

• Mature and stable process, reliable operation

• Adapt to different nature of sulfur slag raw materials

• According to the characteristics of raw materials can be flexibly adjusted process parameters

Scheme B (comprehensive utilization type)

On the basis of Scheme A, add the tailings deep processing system, to achieve the dual objectives of "metal recovery + tailings resource utilization". It not only produces high quality iron ore concentrate, but also processes the tailings into building materials (such as cement raw materials, road base materials, environmental protection bricks, etc.), realizing the full quantitative utilization of sulfur slag and maximizing the comprehensive benefits.

Program Advantage:

• Resource utilization rate reaches 100%

• Create multiple revenue channels

• Completely realize the zero discharge of solid waste

• Meet the requirements of circular economy development

• Enjoy the comprehensive utilization of resources policy support

Choice Recommendation:

• For customers with limited investment budget or mainly focusing on metal recycling, Program A is recommended.

• For enterprises pursuing comprehensive benefits and focusing on environmental protection requirements, Program B is recommended.

• Can take step-by-step implementation strategy, first build program A, later upgrade to program B as needed

Both sulfur slag treatment program adopts modular design, according to the characteristics of raw materials, treatment scale and investment budget for personalized configuration, to ensure the best sulfur slag treatment technology and economic indicators.
