  7. Chalcopyrite (CuFeS2) is an antiferromagnetic semiconductor with unusual magnetic and electrical properties, which are still not clearly understood. Neutron diffraction experiments reveal a phase transition at ∼50 K that has been attributed to an unexpected appearance of magnetic moments on Cu ions, having a paramagnetic arrangement down to 50 K and then ordering to an antiferromagnetic.

Introduction CuFeS2, chalcopyrite, is a well known mineral with an ordered zinc blende structure; its space group is reported to be l~t2D (1). The cell dimen- sions are a= 5.29~ and co = 10. 41,~, and the c-axis is doubled (see Fig. 1). Although commonly found in nature, stoichiometric single crystals of the compound are difficult to prepare ( Chalcopyrite (CuFeS2) DTXSID30156746. Molecular Weight: 187.6 g/mol.

Indonesia has ore reserves of copper (Cu) which is very large, most of the reserves with porphyry Cu content in the ore vary between 0.1-2%. In addition to Cu, usually ore associated with other metals such as gold (A), silver (Ag) and rare metal CuFeS2 + O2 -----> Cu2S + FeO + SO2. 2CuFeS2 + 4 O2 -----> Cu2S + 2 FeO + 3 SO2. First I balance the Cu. Then I distribute the 2 into the Fe and S2 in the CuFeS2 molecule. That will make Fe equal 2 and S equal 4. Next I go to the product side where Fe equals 1 and S equals 2. Balance the Fe with 2 and S with 3. That will balance those but make. The most common source of copper (Cu) is the mineral chalcopyrite (CuFeS2).
