The methods of producing copper from ore include two main methods: pyrometallurgy and hydrometallurgy. The method of pyrometallurgy includes ore extraction, anode melting and casting, and finally, electrolytic refining and obtaining pure copper. In this method, after full grading, the concentrate is melted in the flash furnace and turns into matte copper containing 45% copper. The matte copper is poured into converter furnaces, with the passage of air, impurities (especially iron and sulfur) are oxidized and transferred to slag.

This copper, which contains more than 3.99% copper, is called raw copper or blister copper. Blister copper enters the anode furnace using bottles. In these furnaces, with the injection of propane gas, other impurities are burned together with copper and removed until the purity of copper reaches 7.99%. The output of the anode furnace enters the casting cycle and the anode plates are produced. In the next step, it is converted to 99.9% copper in electrolysis.

In the concentration stage, the slurry passes through the apex in the primary cyclone to concentrate the ore. In the course of purifying concentrates, parts called Apex ceramic parts are used to separate coarse materials from fine-grained materials. Ceramic apexes are anti-wear aluminum parts and their appearance is similar to a funnel. These parts must have very high cold compressive strength along with wear resistance. They should also have very accurate dimensions and angles. As mentioned, ceramic apexes are placed in the passage of concentrate and the use of these parts is to separate concentrate and send slurry from one part to another and they have different shapes.

Since the concentrate particles have high hardness and cause severe wear and tear during transportation, in the process of producing ceramic apexes, parts that have high resistance and tolerance against erosion should be used so that they do not get lost and avoid damages. Financial prevention.

with the highest quality, is ready to provide services to dear customers and send products to all over the country.Achieving the technical knowledge of design and production for the first time in the country after years of research and scientific work to prepare the map based on the obtained documents and the new design has been made based on the existing conditions. Among the innovative features of the product are:

1- The production method in Iran is unique and has been approved by the Iranian Ceramics Association and has led to the receipt of the best craftsman plaque

.2- The type of production process and compression of raw materials from the isostatic press leads to a more controlled microstructure than conventional methods.

3- The use of nano carriers and the presence of mullite connection between the particles that make up the brick lead to a jump in shock resistance.

4- Since the heat treatment takes place below the sintering point and the ceramic connection between the particles occurs due to the chemical reaction of the nano particles with the background phase, so the dimensional tolerance of the parts with this method is very small.

5- One of the features of the aforementioned plan is that the country does not need to import this product. These parts made of silicon carbide are produced by large European companies that do not have the technology to produce recrystallized bands in Iran. By substituting alumina instead of this quality, Atlasseram has made the country free from imports.
