I.　Process　Introduction:　

In　China,　the　existing　borax　pentahydrate　production　processes　include　heavy　crystallization　process　taking　borax　decahydrate　as　raw　material　and　high　temperature　dehydrating　process　taking　borax　decahydrate　as　raw　material.　The　former　has　relatively　high　production　cost,　and　the　latter　has　not　only　high　production　cost,　but　also　difficultly　controlled　process　conditions　and　relatively　poor　product　quality.　Compared　with　imported　products,　both　of　them　lack　competitiveness,　this　is　also　the　key　factor　that　restrains　the　industrial　development　of　Chinese　borax　pentahydrate.　

This　process　takes　borax　ore　or　szaibelyite　ore,　and　ulexite　ore　as　raw　material,　and　achieve　borax　solution　through　submerged　dissolution　or　alkaline　hydrolysis　and　filtration.　Deliver　the　borax　solution　with　adjusted　concentration　to　special　crystallization　system　and　crystallize　under　certain　conditions.　Achieve　finished　product　of　borax　pentahydrate　through　separation,　washing　and　drying.

II.　Technical　Advancement:　

Proprietary　technology.　This　process　does　not　need　evaporation　and　heavy　crystallization,　which　uses　boron　ore　to　directly　prepare　borax　pentahydrate,　overcoming　the　disadvantages　of　heavy　crystallization　process　and　high　temperature　dehydrating　process,　realizing　single-step　method　preparation　of　borax　pentahydrate,　having　low　energy　consumption,　low　cost,　high　quality　and　other　advantages,　and　meeting　the　advanced　international　level　in　quality　and　cost　control.

III.　Market　Prospect:　

Chinese　total　annual　demand　of　borax　pentahydrate　is　above　350,000t,　and　the　demand　has　increased　year　by　year.　Domestic　borax　pentahydrate　production　capacity　is　almost　zero,　the　import　volume　from　Turkey　reaches　260,000t　every　year,　so　the　market　demand　potential　is　tremendous,　and　the　prospect　is　broad.　Please　see　the　attached　article:　Development　Situation　and　Prospect　of　Chinese　Borax　Industry.　

IV.　Technical　Sources:　

Autonomous　research　and　development,　and　industrialization　has　been　realized.

V.　Investment　Scale:　

10,000t/a　is　3.5　million　Yuan,　and　the　scale　can　be　determined　according　to　the　actual　situation.

VI.　Environmental　Protection:　

Comprehensive　utilization　of　boric　sludge　does　not　discharge　waste　residue,　effluent　or　exhaust　gas.

VII.　Product　Quality:　

Borax　pentahydrate　is　produced　with　this　process.　Product　quality　is　as　shown　in　the　table　below.

Item	Indicator	Item	Indicator
Na2B4O7·5H2O　≥%	99.6	Fe　　　　　　　　　　≤%	0.0002
NaCO3　　　　　　　≤%	0.25	Heavy　metal　　ppm	10
SO4　　　　　≤%	0.004	Water　insoluble　　　≤%	0.01
Ci≤%	0.01

VIII.　Economic　Benefits:　

Use　borax　ore　as　raw　material　to　produce　borax　pentahydrate,　and　establish　factory　in　the　place　except　Tibet.　Cost　of　products/t　is　2,900-3,300　Yuan　and　profit　950-1,350　Yuan/t,　so　it　is　very　lucrative.

Comprehensive　cost　evaluation　of　product/t　is　as　shown　in　the　table　below　(factory　is　established　in　Lhasa):　

No.	Item	Content　(%)	Unit　Consumption	Unit　Price　(Yuan　)	Amount　(Yuan　)	Remarks
1	Borax　ore	28	1900　kg	0.9	1710
2	Aid		0.5　kg	12	12
3	Raw　coal		300　kg	1	300
4	Electricity		100kw/h	0.7	70
5	Packaging　material		20　pieces	2.5	50
6	Equipment　maintenance　cost				10
7	Salary				150
8	Water		5m3	4.5	22.5
9	Unexpected　expenses				20
10	Tax				170
11	Total				2514.5

Note:　The　data　in　the　table　are　calculated　based　on　establishing　factory　in　Lhasa　and　resource　conditions　of　Lhasa.　In　case　of　establishing　factory　in　other　region,　the　comprehensive　production　cost　of　product/t　is　within　2,900-3,300　Yuan/t.

IX.　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.　

Our　Institute　can　assist　to　sell　all　products　within　the　output　scope　of　50,000t/year.
