I.　Product　Introduction

Ferric　oxide　has　chemical　formula　Fe2O3,　and　relative　molecular　mass　159.69.　The　appearance　is　red　powder,　having　high　magnetic　conductivity.　High-purity　soft　magnetic　ferric　oxide　is　mainly　used　in　manufacturing　soft　magnetic　ferrite,　and　applied　in　space　flight　and　aviation,　microwave,　carrier　wave,　automobile　electrical　parts,　medical　equipment,　national　defence　engineering　and　other　fields.　With　constant　expansion　of　application　fields,　demand　of　Chinese　market　for　high-purity　ferric　oxide　has　increased　by　15%　on　average　in　recent　several　years.　Domestic　market　gap　in　2009　was　31,000t.　The　market　prospect　is　broad.

II.　Production　Process

This　process　takes　titanium　dioxide　by-product　ferrous　sulfate　or　ferrous　sulfate　solution　as　raw　material,　produces　precursor　of　high-purity　ferric　oxide　through　dissolving,　purification,　precipitated,　dehydrating　and　washing,　then　produce　high-purity　ferric　oxide　product　through　dissolving,　purification,　precipitated,　dehydrating　and　washing.

III.　Process　Features

The　produced　high-purity　ferric　oxide　produced　with　this　process　can　be　used　as　raw　material　of　soft　magnetic　ferrite,　hard　magnetic　ferrite　and　other　industries,　which　is　featured　by　high　product　purity,　good　quality,　simple　process,　little　investment　and　low　cost,　suitable　for　small　and　medium-sized　enterprises　to　invest　and　develop.

IV.　Equipment　Investment

According　to　annual　production　of　1,500t　high-purity　ferric　oxide,　the　equipment　investment　is　about　3.5　million　Yuan.

V.　Evaluation　of　Economic　Benefits

Factory　price　of　high-purity　ferric　oxide　product　is　8,000-12,000　Yuan/t,　production　cost　is　3,450　Yuan/t,　and　the　economic　benefits　are　significant.

VI.　Technical　Form　of　Cooperation　and　Scope

Technical　transfer.　Taking　responsibility　for　process　flow　design,　supporting　equipment　of　standard　equipment,　non-standard　equipment　manufacture　design,　equipment is　plane　layout　design,　equipment　installation　design,　pipe　network　design,　equipment　installation　guidance,　equipment　commissioning,　production　commissioning,　training　for　production　engineers,　analysis　staff　and　technicians,　process　operation　specifications,　raw　material　and　product　analysis　method,　and　preparation　of　intermediate　control　analysis　method;　ensuring　output,　yield　and　quality　to　reach　the　standard;　and　undertaking　turn-key　projects.
