Abstract
The invention relates to a method for continuously synthesizing nickel carbonate, which is characterized by comprising the synthesizing processes: adding and combining a nickel sulfate solution with the concentration of nickel ions from 50 g/l to 55 g/l and a sodium carbonate solution with the concentration from 120 g/l to 125 g/l into a synthesizing kettle according to a flow rate of 1 to 1.2:1, and controlling the pH value of a synthesizing process to be 8.3-8.6 to synthesize the nickel carbonate. The method strictly controls the adding rate of the two raw solutions and the pH values, effectively solves the problems in the prior art that because the excess sodium carbonate solution is added, more local complex salts (Ni1-x/2-y/2Nax(CO3)1-a-b/2(SO4)a(OH)b are generated, the impurity content of the prepared nickel carbonate is higher, the impurities, such as sodium, chlorine, and the like are not easy to be removed in a washing process, thereby effectively improving the product quality of the nickel carbonate, and meeting the requirements of electronic-grade nickel protoxide production and electronic industry.
Description
Technical field
The present invention relates to a kind of method for continuously synthesizing nickel carbonate.
Background technology
Nickelous carbonate is a kind of broad-spectrum Inorganic Chemicals as the important compound of nickel, is mainly used in to make various nickel salts, and nickelous carbonate still is a kind of good presoma of nickel protoxide simultaneously, and high-quality nickelous carbonate can be applicable to the electrical type industry.
At present, most of producer of domestic production nickelous carbonate is that filtrate directly added yellow soda ash without purifying treatment and is precipitated as common nickelous carbonate after nickeliferous assorted material was leached.Nickelous carbonate building-up process pH value is controlled by artificial colorimetric, because the colorimetric card interval of wide pH value test paper is wide, can only carry out the control of integer pH value, observes colorimetric and causes the fluctuation of endpoint pH bigger, and span of control is wide in range.It is excessive to cause the building-up process sodium carbonate solution to add, local double salt (Ni

b) generate morely, the nickelous carbonate foreign matter content of preparation is higher, and impurity such as sodium, chlorine is difficult for removing in washing process, and the nickelous carbonate quality product is low, can not satisfy the requirement of producing electronic-grade nickel protoxide and electrical type industry.
Summary of the invention
Purpose of the present invention is exactly the deficiency at above-mentioned prior art, and a kind of effectively method for continuously synthesizing nickel carbonate of nickelous carbonate quality is provided.
Purpose of the present invention is achieved through the following technical solutions.
A kind of method for continuously synthesizing nickel carbonate, it is characterized in that its building-up process is to contain the nickel sulfate solution of nickel ion 50～55g/l concentration and the yellow soda ash lysate that concentration is 120～125g/l, sodium carbonate solution and nickel sulfate solution are with 1～1.2: 1 throughput ratio and stream add synthesis reactor, control building-up process pH value is 8.3～8.6, carries out synthetic.
Method of the present invention, adopting nickel sulfate solution is that raw material and yellow soda ash lysate are done precipitation agent, according to the influence of degree of supersaturation to precipitated crystal, and the additional proportion and the pH value of two kinds of solution of strict control, effectively avoided existing in the prior art since sodium carbonate solution add excessive, local double salt (Ni
