How did isolate germanium?

In 1886, Winkler was provided with a new mineral from the Himmelsfürst mine near Freiberg. ... After additional chemical purification steps over several months, Winkler isolated the pure element, germanium, on February 6, 1886 and published his results.

How is germanium isolated today?

Today, germanium is primarily obtained from the smelting of zinc ores and from the
byproducts of burning certain types of coal. Both germanium and germanium
oxide (GeO) are transparent to infrared radiation and are used in infrared optical
instruments and infrared detectors.
