I.　Process　Introduction:　

Refine　and　make　pretreatment　for　brucite　ore,　then　produce　magnesium　hydroxide　fire　retardant　through　coarse　crushing,　fine　crushing,　pulping,　super-fine　pulverizing,　modification,　dehydrating,　drying,　grading　and　packaging.　The　production　process　does　not　have　pollution.　Product　quality　is　in　conformity　with　HG/t3607-2000I　standard.

II.　Technical　Advancement:　

Magnesium　yield　is　above　98%.　Product　quality　is　in　conformity　with　HG/t3607-2000I　standard　and　flame-retardant　grade　standard　required　by　user.　It　has　low　production　cost　and　significant　benefits.

III.　Market　Prospect:　

The　present　world　has　increasingly　high　requirements　for　environmental　protection,　environment-friendly　magnesium　hydroxide　fire　retardant　is　emphasized　by　all　countries.　Developed　countries　have　successively　made　huge　investment　in　research　and　development　and　frequently　developed　international　cooperation.　Magnesium　hydroxide　fire　retardant　has　been　widely　applied　in　various　plastic　products,　in　particular,　high　performance　magnesium　hydroxide　fire　retardant　for　wire　and　cable　is　even　popular　among　consumers.　With　rapid　development　of　Chinese　high　molecular　industry　and　constant　perfection　and　improvement　of　flame-retardant　regulations,　the　demand　for　fire　retardant　has　increased　accordingly.　As　non-toxic,　smoke-restraining　environmental　protection　inorganic　fire　retardant,　magnesium　hydroxide　is　in　very　urgent　need.

IV.　Main　Economic　and　Technological　Indicators:　

Production　of　1t　magnesium　hydroxide　requires　brucite　ore　1.11t;　modified　aid　25kg;　coal　130kg;　electricity　450kw·h;　and　water　14m3.　The　production　cost　is　within　1,250-2,600　Yuan/t.　

Market　price　of　the　product　is　3,750-9,000　Yuan/t.

V.　Equipment　Investment:　According　to　annual　production　of　10,000t,　equipment　investment　is　about　2.4　million　Yuan.

VI.　Environmental　Protection:　No　disadvantageous　impact　on　the　environment.

VII.　Form　of　Cooperation　and　Service　Method:　

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.
