High Temperature and Pressure Leaching System

The patented product independently developed by China ENFI is composed of preheater, autoclave, flashing system and is widely applied to the process of large-scale laterite ore, sulphide ore (including cobalt, copper and nickel), refractory gold concentrate, hematite iron removal, copper anode slime and aluminum oxide etc. The excellent quality and stable performance of the equipment has won the customer affirm and trust. Up hold the concept of Safe, Stable and Efficient, replying on the strong technical strength, China ENFI will provide different customers with professional services in the field of pressure leaching technology and equipment.

Pressure leaching process

The raw material (or after preheated) is fed into the auto clave, reacting with reagent (acid, alkali or oxygen) and leached under high temperature（120~260℃） and pressure. After reacting, the material reduced to atmospheric pressure and saturated to boiling point to next process.　　The pressure leaching process is applicable to processing the complex and low grade ore, rapidly and effectively leaching of valuable metals from raw materials, to increase the leaching rate under atmospheric pressure with low energy consumption and friendly environment and comprehensive recovery of valuable metals and realization of slag recovery and utilization.

Preheater

China ENFI independently developed preheater is widely used in sulfide ore pulp and laterite ore pulp preheating system, and can reduce the system consumption of heat source medium and reach higher energy utilization rate. The preheater’s operation and maintenance costs are lower than similar products.

Autoclave

Autoclave is the core equipment of leaching process, and its performance is directly related to the overall operating rate of the system.

China ENFI independently developed autoclave has reached and exceeded the nominal effective work rate. The autoclave can perform well and ensure the stable operation of the plant under severe non-uniform scaling ore pulp system or serious wear and tear conditions. For saving a lot of maintenance cost of enterprises, China ENFI receives praise from clients.

Flashing system

China ENFI has the flashing system technical expertise and improve operating procedures. The system can ensure drive reliable operation in the toughest conditions.
