I.　Production　Principle:　

Calcine　dolomite　under　certain　temperature　conditions,　then　produce　industrial　magnesium　oxide,　high-purity　magnesium　oxide,　active　magnesium　oxide　and　other　magnesium　oxide　series　products　through　digestion,　edulcoration,　kiln　gas　purification　and　compression,　carbonization,　filtration,　pyrolyzation,　separation,　drying,　calcination　and　grading　packaging.　The　waste　residue　generated　in　filtration　procedure　is　magnesium-containing　calcium　carbonate,　after　further　treatment,　prepare　super-fine　light　calcium　carbonate　product.　

Intermediate　product　prepared　during　production　is　basic　magnesium　carbonate,　light　magnesium　carbonate　product　can　be　produced　through　drying,　pulverizing　and　packaging.

II.　Product　Purpose:　

Magnesium　oxide　is　mainly　used　in　manufacturing　ceramics,　enamel,　refractory　material,　etc.;　used　as　filler　during　manufacturing　grinding　material,　adhesive　and　paint;　used　as　accelerant　and　catalyst　in　artificial　fiber　and　rubber　(chloroprene　rubber,　fluorine　rubber);　widely　applied　in　medicine　and　food　fields;　in　building　material　industry,　magnesium　oxide　can　be　used　to　produce　and　manufacture　magnesium-containing　special　cement　and　heat　insulation　board;　in　agriculture,　it　is　used　as　fertilizer　and　feed　addictive;　in　chemical　industry,　it　is　used　in　manufacturing　metal　magnesium　and　magnesium　chemical;　in　environmental　protection　field　it　is　used　in　water　treatment　and　flue　gas　desulphurization;　in　addition,　it　is　also　widely　applied　in　glass,　dye,　electric　cable,　metallurgy,　electronic,　electrician,　insulating　material,　petroleum　addictive,　casting,　phenolic　aldehyde　plastics　and　other　industries.　

Magnesium　carbonate　can　be　used　as　good　filler　and　reinforcing　agent　of　rubber　product　or　heat　insulating,　heat　resisting　and　fire-proof　material.　Light　magnesium　carbonate　is　good　insulating　material,　which　is　used　in　shipbuilding,　boiler　manufacturing　and　other　departments.　In　addition,　it　is　widely　applied　in　advanced　glass　products,　magnesium　salt,　pigment,　paint,　fire-proof　material,　printing　ink,　ceramics,　cosmetics,　toothpaste,　domestic　chemical　and　medicine,　food　and　other　fields.

III.　Equipment　Investment:　

Equipment　investment:　According　to　annual　production　of　magnesium　oxide　1,000t　(magnesium　carbonate　2,500t)　,　equipment　investment　is　6　million　Yuan.

IV.　Economic　and　Technological　Indicators:　　

Medical,　food　grade　magnesium　oxide.　Ton　product　comprehensive　production　cost　(including　tax)　is　about　7,000　Yuan,　and　factory　price　is　15,000　Yuan/t;　

Industrial　grade　magnesium　oxide.　Ton　product　comprehensive　production　cost　(including　tax)　is　about　6,500　Yuan,　and　factory　price　is　9,500-12,000　Yuan/t;　

Industrial　grade　magnesium　carbonate.　Ton　product　comprehensive　production　cost　(including　tax)　is　about　2,500　Yuan,　and　factory　price　is　3,500-4,500　Yuan/t.

V.　Product　Quality:　

Industrial　magnesium　oxide　is　in　conformity　with　HG/T2573-2006　standard;　highly　active　magnesium　oxide　is　in　conformity　with　HT/T3928-2007　standard;　medical　(food)　grade　magnesium　oxide　is　in　conformity　with　the　standard　of　2010　Pharmacopoeia　of　the　Peoples　Republic　of　China;　and　industrial　light　magnesium　carbonate　is　in　conformity　with　HG/T2959-2000　standard.

VI.　Technical　Service　Method　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.
