| Abstract: | Under lanthanum and strontium elements coexistence,continuous determination method of copper and calaium in tungsten concentrate is tested according to the national standard determination method of copper and calcium by AAS.The result shows that copper mass fraction is 0~10 mg/L,calcium mass fraction is 0~15 mg/L,bear's law is obeyed,the recovery of standard addition of copper and calcium are respecively 99%~101% and 96%~103%. |
