Abstract
Correction for ‘Large-scale production of compound bubbles using parallelized microfluidics for efficient extraction of metal ions’ by Heon-Ho Jeong et al., Lab Chip, 2019, 19, 665-673.
The authors regret that Fig. 3B in the original article was incorrect. The correct figure, in which part B has been corrected, is presented herein.
In addition, the units in Fig. 4B, in the insets of Fig. 2, and those in the caption of Fig. 3, are incorrect. Corrected versions of these figures and the corrected Fig. 3 caption, in which mPa has been replaced with MPa, are also presented herein.

Fig. 2 (A) Optical images for generation of core–shell bubbles in 8 parallel FFG. Effect of gas pressure on the coefficient of variation and size (insets) of G/W/O compound bubbles at the middle-phase-and-outer-phase flow ratios (Qm/Qo) of (B) 1![[thin space (1/6-em)]](https://www.rsc.org/images/entities/char_2009.gif) :4, (C) 1:6, (D) 1:8 and (E) 1:10. | ||
