> How can I select each pair of min AND max? I need to iterate over both. Is
it possible?

Apply-templates to all the <min> elements:

<xsl:template match="range">
  <xsl:apply-templates select="min"/>
</xsl:template>

Then in the <min> matching template, apply-templates to the first
following-sibling <max>:

<xsl:template match="min">
  <xsl:value-of select="."/>
  <xsl:apply-templates select="following-sibling::max[1]"/>
</xsl:template>

<xsl:template match="max">
  <xsl:value-of select="."/>
</xsl:template>

You'll have to replace the value-of's with whatever output you need
for the values.
