Please always post a complete example. We have no idea what \textwidth
is, for example, and it is necessary to guess the packages and libraries required to even get something to compile.
It isn't clear what exactly you want aligned as you are specifying a precise aligiment with .58
. If you want the boxes aligned at the top, one way is to use .north east
and anchor=north west
:

\documentclass{article}
\usepackage{multicol,tikz}
\usetikzlibrary{positioning}
\tikzset{
mybox/.style={draw=blue!70!black, fill=blue!5!white, very thick, rectangle, rounded corners, inner sep=10pt, inner ysep=10pt},
fancytitle/.style={fill=blue!70!black, text=white},
}
\begin{document}
\begin{tikzpicture}
% First box
\node [mybox] (box1){%
\begin{minipage}{0.30\textwidth}
\begin{multicols}{2}
\small Alúmina\\Aluminio prim.\\Antimonio (P. M.)\\Arsénico blanco\\Barita\\Bismuto (P. M.)\\Cadmio\\Carbón\\Cobalto\\Cobre (P. R.)\\Cobre (P. F.)\\Fluorita\\Galio prim.\\Germanio metál.\\Oro (P. M.)\\Grafito\\Yeso\\Indio (P. R.)\\Hierro (mena)\\Arrabio\\Acero bruto\\Plomo (P. M.)\\Plomo (P. R.)\\
Magnesita\\Megnesio metál. prim.\\Manganeso (mena)\\Mercurio\\Mica\\Molibdeno (P. M.)\\Níquel (P. R./P.F.)\\Perlita\\Roca fosfórica\\Óx. de tierras raras\\Sal\\Min. de estroncio\\Piritas\\Talco\\Estaño (P. M.)\\Estaño (P. F.)\\Tungsteno (P. M.)\\Vanadio (P. M.)\\Wollastonita\\Zinc (P. M.)\\Zinc (planchas)
\end{multicols}
\end{minipage}
};
\node[fancytitle] at (box1.north) {\textbf{China}};
\node [mybox, right=2mm of box1.north east, anchor=north west] (box2) {%
\begin{minipage}[t!]{0.25\textwidth}
\small Bentonita\\Tierra de batán\\Berilio\\Bromo\\Diatomita\\Caolín\\Gas natural\\Carb. de sodio natural\\Sulfuro (recuperado)\\Telurio metál.
\end{minipage}
};
% Now draw the fancy title (so that it is on top of the connection box)
\node[fancytitle] at (box2.north) {\textbf{EE.UU.}};
\end{tikzpicture}
\end{document}
However, this is not the best way of drawing boxes like this, in my opinion. You would probably find it a lot easier to use something like tcolorbox
. Nesting multiple columns within a minipage
within a node
just cannot be good....
The code above, for example, produces no fewer than 25 bad boxes. The use of \\
to end lines is partly responsible - this ought (very nearly almost) never be used outside tabular
and array
environments etc.
Here's an alternative based on tcolorbox
. It sets up a new environment listingbox
with the following syntax for a one-column box:
\begin{listingbox}[<additional options for box>]{<title>}
<contents>
\end{listingbox}
or the following for a two-column version using the starred version:
\begin{listingbox}*[<additional options for box>]{<title>}
<column one>
\tcblower
<column two>
\end{listingbox}
You can then say:
\begin{listingbox}*[width=.4\textwidth]{China}
Alúmina\par Aluminio prim.\par Antimonio (P. M.)\par Arsénico blanco\par Barita\par Bismuto (P. M.)\par Cadmio\par Carbón\par Cobalto\par Cobre (P. R.)\par Cobre (P.

EDIT
For many boxes arranged similarly to your sample image, you can use minipage
s to create vertical columns from several boxes:

library is required for that syntax, and you'll see the Martin Scharrer has that in his preamble in the other question. – Torbjørn T. Oct 6 '15 at 15:29
