江特电机碳酸锂量产 吨毛利近10万元

2017-09-25 08:07:53   中国经济网

针对市场上有关江特电机多年从事锂行业,新生产线工艺大概率不成熟,锂云母无法量产的相关质疑,辛毅敏表示,公司之前采用硫酸法,锂云母和硫酸的比例是一比一,对设备腐蚀性大,生产稳定性不够。今年公司对工艺前端进行技改,采用焙烧法,锂提取率从原来的45%,提升到80%。新工艺改进对设备影响小,生产开始稳定。而且,生产出的电池级碳酸锂产品经检测符合国家标准,批量生产获得成功,锂云母提锂技术取得重大突破。

“新生产线的成功,给公司下一步扩产碳酸锂奠定信心。”江特电机证券事务代表王乐对中国证券报记者表示,银锂新能源公司的二期项目正在建设,预计明年上半年可以投产,年产1万吨碳酸锂。

“锂云母矿选矿厂正在建设中,短期内较难满足大规模碳酸锂对锂云母原料的要求。公司已经和宝威物料合作,利用宝威物料包销的价格优惠的锂精矿原料供应,建设年产1.5万吨碳酸锂及氢氧化锂产线。预计明年上半年可正式投产,2018年公司锂盐产能将达到3万吨。”王乐介绍。

碳酸锂成本优势明显

目前江特电机的锂云母主要来自414矿区、泰昌矿业(年选矿能力80万吨,折合8万吨锂云母)和宜丰矿区。其中,宜丰矿区一期项目预计今年年底建成,明年一季度投产,一期大选矿能力60万吨。

“宜丰矿区的基建和厂房是按照120万吨的选矿能力建造的,之所以把产能下降到60万吨,是由于陶瓷市场不景气和环保因素。”江特电机董事卢顺民告诉中国证券报记者,“120万吨锂瓷石只能提取12万吨锂云母,剩下108万吨的长石粉(主要用于陶瓷),市场较难消化,只能堆料,这又影响到环保。不过,目前锂云母价格从原来每吨800元涨到2000元,效益明显,公司对该项目将按原规划产能设计。”

据了解,目前国内提锂主要是矿石提锂和盐湖提锂。盐湖提锂成本最低,大概每吨在5万元。但由于自然因素(降雨、洪水等)和人为因素(技改检修)等,短期内产量无法大幅增长。业内普遍预计到2019年-2020年盐湖提锂产能才有望大幅提升。

矿石提锂有锂辉石提锂和锂云母提锂两种。锂辉石基本来自国外,精矿品位大概5%-6%。锂辉石精矿目前价格在每吨1000美元左右,按照8吨锂辉石精矿生产1吨碳酸锂计算,原料成本就到5.6万元-6万元,再加上两万多的制造成本,整体的成本在8万元左右。

辛毅敏告诉中国证券报记者,目前4%品位的云母精矿价格在2000元/吨左右,公司碳酸锂吨耗目前控制在14-15吨之间,原料成本控制在3万元左右,但加工成本比锂辉石稍微高一点,差不多是每吨3-4万元,整体成本可控制在每吨7万元左右。
